-Unimplemented Functionality
----------------------------
-
-We don't support interruptible functions. That is, if a signal is
-delivered when a thread is in e.g. the write system call, then the
-write function should be interrupted and return EINTR when the signal
-handler is finished. To realize this behavior, we could have a thread
-local interruptible flag and a setjmp buffer. A function that is
-interruptible would fill the jump buffer and set the interruptible
-flag. If a signal comes in and the interruptible flag is set, rather
-than resuming the thread, we longjmp to the buffer.
-
-If a signal action has set the SA_SIGINFO, the third argument must be
-a pointer to a ucontext describing the thread's interrupted state;
-this implementation passes NULL. This isn't as bad as it sounds as
-the the ucontext family of functions are marked obsolete in SUSv3 with
-the advisory that any use of them should be replaced by the use of
-pthread functionality (cf. makecontext rationale).
-
-stop and continue signals are not implemented (as we need to stop all
-threads, this requires being in bed with libpthread).
-
-Implementation is not yet cancellation-safe.
-
-There are not even stubs for sighold, sigingore, sigpause, sigrelse,
-however, according to posix: "Use of any of these functions is
-unspecified in a multi-threaded process."
-
-Implement sigtimedwait, sigqueue. \ No newline at end of file
