One approach would be to have a "monitor" process that forks the "event 
consumer" process. If the event consumer process terminates, the monitor 
process would restart another one. The monitoring could be with a 
semaphore that the event consumer signals in an unwind block. The 
monitor process could also watch a flag to see if the event consumer 
should be terminated or restarted.
