It was quite reproducible on my dual 1.8 G5 at work.  I can't even =20
open or create a new project document on my G4 PowerBook at home, =20
though, which is very strange.  I get a beachball with the following =20
sample snippet (until it runs out of memory).  This is with iTM2p13.

NSTask and threads don't play well together, unfortunately...we use a =20=

threadsafe task wrapper and message queue in BibDesk for its TeX =20
preview, which helped quite a bit.

I tried the build scripts, but ended up with build products in my ~/=20
BuildProducts directory, so linking failed early on.  The Omni =20
frameworks use xcconfig files pretty heavily, so I might take a look =20
at their build script.
