Issue #11223: skip test_lock_acquire_interruption() on FreeBSD6

Victor Stinner · Victor Stinner · commit f25ae48dfd64 · 2011-06-23T11:57:56.000+02:00
Locks are implemented using a mutex and a condition variable of the pthread
library on FreeBSD6. POSIX condition variables cannot be interrupted by signals
(see pthread_cond_wait manual page).
