does TAKETHIS wait for a response?

[Anne Wilson]

Thanks, Russ!

I still, however, need to know for sure how responses to TAKETHIS are 
handled.  How often are responses sent for TAKETHIS?  Does innfeed wait 
for them?   It probably doesn't wait, but in that case how are they 
handled?  Maybe responses are only sent infrequently, or maybe responses 
are handled in a batch manner.

I may wind up instrumenting the code a bit to figure this out.  But, 
that'll have to wait until next week as I'm taking a short vacation.

Later!
