Add 'module-body-inside-context, 'module-body-outside-context, and
'module-body-context-simple? properties to the expansion of a
`module` form. These properties expose scopes that are used by
`module->namespace` and taht appear in marshaled bytecode.
The expression in a `define-runtime-path` form is used in
both a run-time context and a compile-time context. The
latter is used for `raco exe`. In a cross-build context,
you might need to load OpenSSL support for Linux (say)
at build time while generating executables that refer to
Windows (say) OpenSSL support. In that case, `#:runtime?-id`
lets you choose between `(cross-system-type)` and
`(system-type)`.

In particular, instead of going directly back to the chaperone, handle
the case where the function doesn't accept keyword arguments with a
less expensive fallback.
The less expensive fallback uses a case-lambda wrapper (wrapped inside
a make-keyword-procedure) to close over the neg-party and avoid the
chaperone creation. With this commit, the program below gets about 3x
faster, and is only about 20% slower than the version that replaces
the "(let ([f f]) ...)" with its body
#lang racket/base
(module m racket/base
(require racket/contract/base)
(provide (contract-out [f (-> integer? integer?)]))
(define (f x) x))
(require 'm)
(collect-garbage)
(time (for ([x (in-range 5000000)]) (let ([f f]) (f 1))))
Thanks, @samth!
OS X's libssl is deprecated, and it doesn't work with SSL connections
that need SNI. We'll distribute out own libssl builds for OS X via a
package, but we need a native implementation that works well enough to
get that package.
The 'secure protocol symbol is just a shorthand for
`(ssl-secure-client-context)`, but it helps highlight
that the default 'auto isn't secure, and having a plain
symbol smooths the connection to native Win32 and OS X
implementations of SSL.
The getdtablesize() result appears not to be constant on OS X.
Creating some combination of CFStream objects, threads, and CFRunLoop
objects can cause the value to be increased by a factor of 10. Avoid
the need for getdtablesize() by switching from select() to poll().
