Content
Here's a patch skipping testFDPassSeparate and testFDPassSeparateMinSpace on OS X < 10.5, due to known kernel bugs (see http://developer.apple.com/library/mac/#qa/qa1541/_index.html). For InterruptedSendTimeoutTest and testInterruptedSendmsgTimeout, it also looks like a kernel bug. There could be another explanation, though: if, for some reason, other threads are running at that time, the signal might be delivered to another thread, and our main thread remains stuck on sendto/sendmsg once the socket buffer is full. I'm however not sure why this would only affect OS X (since FreeBSD behaves in the same way when it comes to signals, contrarily to Linux). Also, I'm not sure why this would not affect recv/recvmsg.
