process stuck in a sched_yield() loop

Can somebody with the necessary skills help me with this?

$ cd /usr/ports/devel/libinotify/ && make clean fake && make test


I remember this used to work... Now, most of the times, the
'check_libinotify' process brings the CPU to 100% and it's stuck
in a sched_yield() loop:
