Subject: [patch 0/4] ipc sem improvements

Hi, this patchset is some improvements I've been trying to make to sysv
semaphore implementation which is pretty suboptimal (O(n^2) behaviour
with n waiting processes, among other things).

I've been quite careful to try retaining fifo and avoiding starvation
even for complex operations.

Comments?

Thanks,
Nick
