/*
* our delay API
*
* zeroconf requires us to have things outstanding on the network
* and to wait until a certain amount of time has passed before
* proceeding.
*
* This API tries to be somewhat sane to use but it has limitations,
* like it needs to have SIGALARM handled specially. It can only
* have a single delay outstanding at once. Delays are always against
* observed real-time
