    hs_exit()/shutdownHaskell(): wait for outstanding foreign calls to complete before returning · 681aad99

    This is pertinent to #1177.  When shutting down a DLL, we need to be
    sure that there are no OS threads that can return to the code that we
    are about to unload, and previously the threaded RTS was unsafe in
    this respect.
    When exiting a standalone program we don't have to be quite so
    paranoid: all the code will disappear at the same time as any running
    threads.  Happily exiting a program happens via a different path:
    shutdownHaskellAndExit().  If we're about to exit(), then there's no
    need to wait for foreign calls to complete.
