Perhaps we need a flag bit, SA_NOINTR maybe, that specifies that the
signal is not to interrupt a syscall in progress?
I'm not sure how this could be made to interact well with syscalls such
as wait and sigpause that are *designed* to be interrupted by signals,
but something like it looks appropriate for things like fsck and dd.
