Matthew Flatt 4d76aa2040 place channels & threads: improve GC 
Allow a thread to be GCed when it is blocked on a place
channel for reading and the place channel's write end
is inaccessible.

GC is limited to threads that do not participate in cycles
of such threads, where the otherwise unerachable threads
are blocked on place channels that are reachable among the
set of threads. In other words, the GC finds the greatest
fix point (as measured by the threads to retain) instead of
least fix point --- which isn't what you want, but finding
the least fix point seems to require significant extra GC
machinery across places.

This improvement was intended to solve the same problem as
commit 7b0608c, but that case seems to run into the limitation
on cycles.
