Yes.

No. It happens even if you don't link with "-lc_r", but as the current
"-lc_r" on {Free,Net,Open}BSD is a user-mode library using "select()" or
"poll()" in its main loop, one consequence of the bug is that BPF (and
hence libpcap) don't work correctly in multi-threaded programs.
OpenBSD has, I think, had a fix for this for a while, and I think a fix
was checked into FreeBSD -current recently and MFCed.
