Hi,

When the EPICS foreground thread is not the main thread(started by main(...)),
it ends up with segmentation fault when I tried to shutdown my
application gracefully (trace showed it happened at the last line: "exit(0)".

Quick look at the "ca" code, maybe it is caused by atexit( ).

The fault disappeared after I changed code to let the main thread
create the context and let the EPICS foreground thread join it.

I am implementing a gateway to EPICS for a popular user interface
of synchrotron x-ray (DCSS/Blu-Ice: http://smb.slac.stanford.edu/blu-ice/)
It automatically configures the mapping from the DCSS server.
Update messages from EPICS can be merged at a configurable rate
to avoid saturate the DCSS server.
