.SH "DESCRIPTION"
.PP
Send a command from interrupt state. If there is a command
currently being executed then we return an error of -1. It
simply isn't viable to wait around as commands may be
slow. This can theoretically be starved on SMP, but it's hard
to see a realistic situation.  We do not wait for the command
to complete --- we rely on the interrupt handler to tidy up
after us.
