This is true only when a signal is pending.
It is the signal dispatch code that fixes up the return value
either by changing it to -EINTR or by resetting the register
state such that the signal handler returns to re-execute the
system call with the original set of argument register values.
If a signal is not pending, you risk leaking ERESTARTSYS to
userspace.
