Any code that can block/run for unbounded time (in extention code)
and you wish to interrupt after a certain time out.
One thing where it could be usefull is the Queue module.
AFAIU the Queue module doesn't block on a full/empty queue when
a timeout is specified but goes in a loop sleeping and periodically
checking whether place/items are available. With signals that
can be sent to a thread the queue could just set an alarm and
then block as if no timeout value was set and either unblock
when place/items are available or get signalled when the timeout
period is over.
