Like @code{signal} (@pxref{Signaling Errors}), but the signal is
delivered in the thread @var{thread}. If @var{thread} is the current
thread, then this just calls @code{signal} immediately.

thread, then this just calls @code{signal} immediately. Otherwise,
@var{thread} will receive the signal as soon as it becomes current.

@code{condition-wait}, or @code{thread-join}; @code{thread-signal}
will unblock it.
