I would like to argue against checking groups post mkgroupfile
and for checking groups during mkgroupfile

This message would have been more informative with the offending
test file.

Now after you crunched all the test files into group.list files and
all the group.list files into a unique group set, this is too late.
But this same check during generate_groupfile() would have
been trivial and would allow reporting the offending test.

While we are on the subject of generate_groupfile(), can you please
explain the rationale behind the method of extracting the test file
groups by executing the test with GENERATE_GROUPS=yes?
As opposed to just getting the list of groups on the stop from the file
using grep?

Thanks,
Amir.
