Indeed.  My very first production erlang code went into service
as an embedded system.  It was a half call model system where
there was a call state finite state machine for each logical
channel.  When I got aroud to looking at the logs a few days
later I found that every call through the system had result in
a process crash.  The crash was happening during call teardown 
so it wasn't noticed by anyone.  The supervisor simply started
a new gen_fsm in the idle state and the next call was handled 
as normal.  I was quite impressed at the time because although 
I understood the theory seeing it work in a real sense was 
something else.
