The main problem was that when a place catches an exception,
it would continue in breaks-disabled mode. Also improve
`parallel-do' to detects additional breaks when waiting on
places and propagate them, in case a place was running something
that ate the initial break.
Fix memory accounting to detect when messages pile up in a
place channel and when shared values (such as the result of
`make-shared-bytes') pile up. Also fix problems where a GC
or free-page purge needs to be triggered.
The implementation causes a minor API change, which is that
a place channel sent multiple times as a message generates
values that are `equal?' but no longer eq?'.

After all the previous attempts, the problem seems almost trivial:
although Apple documents `NSAnyEventMask' as the constant #xFFFFFFFF,
it's actually NSUIntegerMax (and the difference matters in 64-bit
mode).

In particular, instead of trying to collect all of the arrows and do some kind
of a smart transitive closure (that tries to avoid adding links that would "skip"
expressions but doesn't always manage it), the new code tries instead to build
the right links directly while traversing the fully expanded expression
This also seems to have been a minor performance improvement. When running the
information collection phase of check syntax (ie, not counting the time for
expansion) on a 1.8 GHz core i7, for collects/framework/private/text.rkt,
the times went from:
cpu time: 7347 real time: 7413 gc time: 211
cpu time: 7328 real time: 7393 gc time: 239
cpu time: 7356 real time: 7418 gc time: 240
to:
cpu time: 7562 real time: 7632 gc time: 265

Reordering `unsafe-vector-ref' past an `unsafe-vector-set!' was
particularly bad. Meanwhile, some non-mutating operations like
`unsafe-mcar' were treated too conservatively.

The FFI's weak table of callback procedures (to map Racket procedures
to FFI callback objects) suffered from the classic key-in-value
problem.

The bug was that a procedure could be incorrectly marked as
a "leaf" procedure, which could in turn cause the compiler
to keep inlining a very small procedure that calls itself.

Specifically, in the case that we're inheriting a language setting
from some earlier preference or something and the language we're
inheriting is one that saves prefixes, and the current file being
opened does not match any of the possible prefixes, then revert
to the not-a-language language, instead of using the value from
the preference
Also: finish the removal of the EoPL language level from the
DrRacket langauge dialog, and clean up the 'get guidance' dialog
Please cherrypick this commit to the 5.2 release branch
'read-language' uses as a single token in the case that read-language
fails. This helps it to deal with things like s-exp and at-exp
properly

This fix uses the same`run'-vs-`finishLaunch' technique as before,
but patches up the modal-dialog problem by calling `run' again
with a callback to start a modal loop.
