I thought so, too, but...

I observed several failures in tests.
Let's see if I can find some:

Here is one:

http://hudson.modula3.com:8080/job/cm3-current-test-m3tests-I386_SOLARIS-opencsw-current10x/11/console

Perhaps the cm3 used there was still too old?
I'm sure there were more, but I cannot find them right now.

If you're sure it's fixed, we can try it again, no problem.

What about the hanging test p037 on Solaris 2.9 though?
See  
http://hudson.modula3.com:8080/job/cm3-current-test-m3tests-SOLsun-opencsw-current9s/8/console

Any ideas?
