Re: [9fans] drawterm osx-x11 on x86_64

Well, I wrote `the current sources', but that was wrong: I just
checked bitbucket again and saw your commits of the last few hours. So
I pulled the updates and rebuilt. To my surprise, the phenomena remain
exactly the same. This time I got a message though:

objc[3785]: Object 0x7fb261297930 of class NSConcreteMapTable
autoreleased with no pool in place - just leaking - break on
objc_autoreleaseNoPool() to debug

Mark.
