But then the existing pre-emption check is also meaningless, since
redisplay (due to output buffering) will usually complete before more
input arrives.

At least, I don't think it will be any worse ... and btw, it also
adapts pre-emption to the actual cpu load on the local systems.

Does the X protocol buffer requests like that? Last time I looked,
it didn't do much buffering before transmitting on the wire. But
IIRC, there may be some X-aware protocol which does buffering.

I'll do that.
