Threads and SIGSEGV

Python 2.3.3, Linux 2.4.x:

It looks as if a SIGSEGV in a thread of a multi threaded
application does not kill the complete process under some circumstances
but only one thread (unrelated to the original SIGSEGV).

Although documented this way, this is arguably the wrong behaviour
for SIGSEGV (and some other signals that indicate program failure).
