Signals will be delivereed if a syscall is exited. There are two ways for a
syscall to wait for sometihing. Interruptible and uninterruptible.
Geneerally all uninterruptible sleeps should be avoided, but sometimes it is
necessary (to avoid raceconditions or reentrance problems). Syscalls can
check for signals and exit to allow delivery, in any case the developer has
to take care that something is interruptible reasonable.
