    Don't use this implementation when Py_AddPendingCalls() can happen

    There are two possible race conditions:
    (1) nested asynchronous calls to Py_AddPendingCall()
    (2) AddPendingCall() calls made while pending calls are being processed.
-   
+
    (1) is very unlikely because typically signal delivery
    is blocked during signal handling.  So it should be impossible.
