Running screen-3.9.4-3 or screen-3.9.5-4 utilizes 95-99% of CPU.
Could you give me more info, I can't reproduce.
A good test case would be nice.
Works fine on an IBM ThinkPad 240 (Celeron 300Mhz).
Eats up 99% of CPU time on a SCSI-based, Pentium III 600MHz workstation.
I can provide strace output of both on request.
Please, give me some straces then.
Screen is pretty much broke by design,
but it's the only thing that does what it does.
