FYI -- I have reproduced all the problems but am still looking at it.
I thought perhaps it would be something about the globsearch's
invocation of python, but it's not -- I get the same thing even with
gmake's native filter (and in fact, it appears to be worse).
I'm getting something funny in the counts directory which is where each
individual run stores its output, but I need more testing to figure out
what's going on.

I don't know how this would happen and haven't noticed it myself.
Perhaps Scott can help investigate. It would help to know which tests
run in each case. To debug, I would make a dry-run or skip-all mode
that skips actually running the tests and just reports success (or
skip).

The print-test target seems ok wrt race conditions

However, if I run the tests, I get two different outputs

Scott,
I have noticed that make -j20 -f gmakefile.test test globsearch="mat*" does
not always run the same number of tests. How hard is to fix this race
condition in the generation of the rules?
Can you reproduce with the print-test target? These are just running
Python to create a list of targets, and should all take place before
executing rules.
