You might want to review the thread from this list back around 20th June 
this year, under the subject line

Worth reading, but the summary is that Geoff Canyon suggested
   wait 0 msec with messages

(you don't even need to wait a whole 1 !!)

Glad you found this - I was part-way through mentally composing quite a 
long reply, I just hadn't got to a keyboard yet - so this saves me some 
typing.

I'm still concerned about the fact that you said moire would interfere 
with other apps.

It should be up to the OS to limit the impact any one app can have on 
any other one by grabbing all the CPU - and as far as I know even Win 
does this OK, except for the problem of filling memory, and hence 
requiring large changes in page set to switch between apps. Is it 
possible that you saw those problems where the Rev stack was memory 
intensive as well as CPU intensive ?
