Just a quick note in case anyone else is wondering before updating OS X. My experience so far has been that drawterm-cocoa has issues when full screen which make it unstable (it'll work for a while, then drawing gets flickery, then it crashes). This *seems* to be triggered by switching OS X workspaces. I've been using it windowed and it's been stable for hours now.
Existing p9p binaries seem to mostly run fine (including full-screen drawing), but rebuilding is failing. I'm too sleepy to track down why just now. Anthony
