Yes (At least if the send was RMPP'd). That's what started this thread.
Not sure about normal MAD send of those. Sean ?

The semantic of timeout for RMPP send appears to me to be different.

I'm not sure what a consumer would want a timeout to a non request
method.

Other alternatives are:
Change RMPP send timeouts to be same as normal MAD sends
or
Not return entire send packet on timeout. Is that a requirement also ?
