Oh how I hate signals... this can get scribbled by a syscall/fault from
sigcontext :/

Maybe I can recover the timo argument from the original syscall
pt_regs.. let me try.

I don't think we need to do anything special with timeouts if a signal
happens - just normally return -EINTR (after a resume from a server)
and let the userspace figure things out.

Alternatively, in my version of the patchset UMCG tasks ignore
non-fatal signals. :)
