David,

I took a quick look on a quad core 2 box running Fedora Core 10 and the
Squeak 3.7-7 VM and 3.10.2 image. It seems to lock up on "RemoteTask
result". Running the Tests-OSProcess does indeed cause one failure in
#testCooperatingProcesses04 where the tests for version 43 were all
green. Running Tests-CommandShell locks up after 71 tests with one
failure (version 4.3 had all green tests after I created a /usr/bin/vi
file).
