[M3devel] AMD64_DARWIN head formsedit sometimes hangs starting up

Sun Dec 6 15:31:13 CET 2009

formsedit startup seems to often hang in the debugger, in head.

The one obvious guess is that the thread trying to take the heap lock is waiting forever and not responding to the suspend.
I should probably go back and test I386_DARWIN and PPC_DARWIN instead? (and release branch)
