-// When the default version of close used on Mac OS X fails with EINTR, the
-// file descriptor is not in a deterministic state. It may have been closed,
-// or it may not have been. This makes it impossible to gracefully recover
-// from the error. If the close is retried after the FD has been closed, the
-// subsequent close can report EBADF, or worse, it can close an unrelated FD
-// opened by another thread. If the close is not retried after the FD has been
-// left open, the FD is leaked. Neither of these are good options.
-//
-// Mac OS X provides an alternate version of close, close$NOCANCEL. This
-// version will never fail with EINTR before the FD is actually closed. With
-// this version, it is thus safe to call close without checking for EINTR (as
-// the HANDLE_EINTR macro does) and not risk leaking the FD. In fact, mixing
-// this verison of close with HANDLE_EINTR is hazardous.
-//
-// The $NOCANCEL variants of various system calls are activated by compiling
-// with __DARWIN_NON_CANCELABLE, which prevents them from being pthread
-// cancellation points. Rather than taking such a heavy-handed approach, this
-// file implements an alternative: to use the $NOCANCEL variant of close (thus
-// preventing it from being a pthread cancellation point) without affecting
-// any other system calls.
-//
-// This file operates by providing a close function with the non-$NOCANCEL
-// symbol name expected for the compilation environment as set by <unistd.h>
-// and <sys/cdefs.h> (the DARWIN_ALIAS_C macro). That name is set by an asm
-// label on the declaration of the close function, so the definition of that
-// function receives that name. The function calls the $NOCANCEL variant, which
-// is resolved from libsyscall. By linking with this version of close prior to
-// the libsyscall version, close's implementation is overridden.
