python bittorrent broken with feb 5 (libpthread) freebsd

As the subject says, python bittorrent is broken when linked to libpthread. If I
force python to link to libc_r in /etc/libmap.conf, it works fine. Here is the
output of an ldd on python before libmap.conf changes:

/usr/local/bin/python:
        libpthread.so.1 => /usr/lib/libpthread.so.1 (0x28112000)
        libutil.so.4 => /lib/libutil.so.4 (0x28135000)
        libstdc++.so.4 => /usr/lib/libstdc++.so.4 (0x28140000)
        libm.so.2 => /lib/libm.so.2 (0x281f2000)
        libc.so.5 => /lib/libc.so.5 (0x2820a000)

It doesn't link to both libc_r and libpthread, so this looks like a bug in
libpthread. I'm not sure what other info to give here, so if someone wants to
tell me what other info is necessary to help fix this problem, let me know. All
that needs done to reproduce this problem is try to use the bittorrent curses
client to download anything. It gets stuck at "connecting to peers" and won't
respond to a ctrl-c.
