I stand corrected. Signals get delivered on return from a system
call *or* on return from an interrupt. (But on systems configured with
CONFIG_NO_HZ, it could be a while before there's an interrupt, couldn't it?)
I guess the worst case is the signal will be delivered at the beginning
of the next time slice, so that shouldn't be too long.
