One thing that strikes me as a problem is transitory resources used
by tests. I know I have a number of modules that will create
(deleting if they already exist) various files during their run

Each test is still independent (they randomize just fine) but if
you ran two at the same time they could wallop each other's data.
Short of running each test in some sort of transactional file
system (do such things exist? Are they common?) or cloning the
build directory before each test, the only solution I can imagine
is some sort of thing in the (Makefile|Build).PL that explicitly
states that the tests are allowed to run in parallel, which can
then be passed on to the testing process...
A solution might be to use File::Temp::tempdir(CLEANUP => 1) in that
case. You can build the whole tree of files per-test and wipe clean
upon exit. It seems to me that writing temp files to the build dir
should be discouraged.
