Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://www.squeaksource.com/VMMaker/VMMaker-oscog.12.mcz

==================== Summary ====================

Name: VMMaker-oscog.12
Author: eem
Time: 22 June 2010, 9:51:54 am
UUID: a34fa6af-c3a0-453e-8450-8525342057ac
Ancestors: VMMaker-oscog.11

Fix co-routining and cannotReturn: crashes.  Key is to arrange
that when baseFrameReturn returns to a frame in the middle
of a stack page the frames above it (which may be in use in
coroutining) are preserved, i.e. by movign them to another
page.

Fix simple blocks with temps.  JIT compiles simple blocks
without a stack frame and so the stack must balance.  The
JTI must strip any leading pushNils that initialize temps
otherwise these will be interpreted as return addresses
causing a jump into la la land.

Various typos and niceties from mainline Cog.
