How about an MCA parameter to switch between this mechanism (early
sendi) and the original behavior (late sendi)?
This is the usual way that we resolve "I want to do X / I want to
do Y" disputes. :-)
I see the smiley face, but am unsure how much of the message to
apply it to.
It applied to that sentence only -- the proposal was genuine.
Assuming the MCA proposal is genuine (easy for implementor
consensus? or easy for the user? gee, lemme see, that's a tough
choice...), I'll note that it's easy enough to do. I've implemented
the early-sendi-check by adding a function to ob1 to do the right
thing. So, I can call that function as soon as one enters the PML
send. The "late sendi" call is at a different call site. So, one
call site for "early sendi" and another for "late sendi". Easy to
turn on/off. We're not talking about many small codes changes
pervading the source base.
True, but Brian hated it. :-)
How about Brian's proposal?
