... You might want to take a look at:

and comment on its effectiveness. It fixes the original problem that lead to having signals blocked in spawned threads. (The problem essentially being that a Control-C in readline might be caught by the wrong thread.) but without the blocking. (besides the segfault problem, it also fixes the way that os.system() and os.popen() spawn children with blocked signals, and similar problems.) It does so in a more general purpose way that should help python on all supported platforms, and not just the specifics of LinuxThreads.
Note the following extract from the Python Library Reference doc-2.3/lib/module-signal.html: .... and the main thread will be the only one to receive signals (this is enforced by the Python signal module, even if the underlying thread implementation supports sending signals to individual threads). Thus, beside the "Control-C" issue, we respect/update this assertion about signal delivery. -- Dieter
