[Leonid Evdokimov]

I confirm the bug.

Deadlock at Linux 2.6 (^C does not work):
Python 2.4.4 (#1, Jan  8 2008, 23:42:40) 
[GCC 4.1.1 (Gentoo 4.1.1-r3)] on linux2

Sometimes work and sometimes fails with fatal error at FreeBSD 6.3:
Python 2.4.4 (#2, Oct 31 2007, 05:20:42) 
[GCC 3.4.6 [FreeBSD] 20060305] on freebsd6

before Popen
before first line
FFatal error '_pq_insert_tail: Already in priority queue' at line 200 in
file /usr/src/lib/libpthread/thread/thr_priority_queue.c (errno = 0)
after last line          

And sometimes it deadlocks and ^C shows same traceback Ralf Schmitt
already posted.
