// ---------------------------------------------------------
// - Small utility lib for sending messages from C through
// - the PULSE scheduler.
// -
// - The caveat is that you can't send messages to a named/
// - registered process from a NIF. Therefore a little bit
// - of machinery is used to keep track of the Pid of PULSE
// - and to enable message sends to PULSE via the pulse_send
// - function.
