    Fix issue #1590864, multiple threads and fork() can cause deadlocks, by
    acquiring the import lock around fork() calls. This prevents other threads
    from having that lock while the fork happens, and is the recommended way of
    dealing with such issues. There are two other locks we care about, the GIL
    and the Thread Local Storage lock. The GIL is obviously held when calling
    Python functions like os.fork(), and the TLS lock is explicitly reallocated
    instead, while also deleting now-orphaned TLS data.

    This only fixes calls to os.fork(), not extension modules or embedding
    programs calling C's fork() directly. Solving that requires a new set of API
    functions, and possibly a rewrite of the Python/thread_*.c mess. Add a
    warning explaining the problem to the documentation in the mean time.

    This also changes behaviour a little on AIX. Before, AIX (but only AIX) was
    getting the import lock reallocated, seemingly to avoid this very same
    problem. This is not the right approach, because the import lock is a
    re-entrant one, and reallocating would do the wrong thing when forking while
    holding the import lock.

    Will backport to 2.6, minus the tiny AIX behaviour change.
