Hi Andrew,

Thanks -- I'll gladly take all the advice you can give on this!

I find that if I create channels inside Python threads they do have
new contexts (that is other than the initial one), even without
asking.  Doing
   ca_create_context(); create-and-use-channels ; ca_context_destroy()

within a thread seems to work fine.

In order to have all processing done in one context, I have to
explicitly get the initial context in the main thread, and pass this
into each thread.  That seems like extra work for the user.   If
that's the recommendation,  would it be reasonable to have ca.py make
sure to attach to the initial context (if needed) prior to any
processing?

Is there a use-case for multiple contexts on the client side?

Thanks,
