Public bug reported:
In thinking about https://github.com/pyepics/pyepics/issues/171 I did a
quick test of adding prints to the (dis)connection and event callbacks
in camonitor.c and find that the thread making the disconnect callback
does not (always?) have a CA context associated with it. This means
that a disconnect callback which uses functions which implicitly pick up
the CA context (like ca_pend_io() ) can implicitly create (and leak) a
new context each time.
In my test I find that the disconnect callback is happening on a TCP
send thread.
