* macosx/tclMacOSXNotify.c (Tcl_WaitForEvent): if the run loop is
already running (e.g. if Tcl_WaitForEvent was called recursively),
re-run it in a custom run loop mode containing only the source for the
notifier thread, otherwise wakeups from other sources added to the
common run loop modes might get lost; sync panic msg changes from HEAD.
* unix/tclUnixNotfy.c (Tcl_WaitForEvent): on 64-bit Darwin,
pthread_cond_timedwait() appears to have a bug that causes it to wait
forever when passed an absolute time which has already been exceeded by
the system time; as a workaround, when given a very brief timeout, just
do a poll on that platform. [Bug 1457797]
