That is, if I understand blocking correctly. Currently assuming that blocking only happens when two things would like to write the same ref?
Blocking in this case refers to this definition: http://en.wikipedia.org/wiki/Blocking_(computing)You should use "send-off" if any of the operations in the action may cause the the thread it runs in to "block" (sleep) while waiting for something. That something is often I/O completion, but a thread can also block waiting to acquire a lock, or waiting for a time interval to elapse.
If anything in the action requires waiting, use send-off, otherwise use send.
