Hi,
When using the Linux Skype client under FreeBSD I sometimes see that the
Audio disappears in the one direction. When I check "ps auxw" I see
skype is stuck on a so-called Futex. I looked into the Linux futex code
and see that wakeup_one() is used instead of wakeup(). Maybe others can
test too and verify if replacing wakeup_one() by wakeup() makes any
difference in for Linux applications using Futexes.
