What's the difference between passing -m or -p and not passing any
option at all?  The following all run the same number of tests at the
same speed afaict:

./bin/test -p lp.codehosting.vfs.tests -u
./bin/test -m lp.codehosting.vfs.tests -u
./bin/test lp.codehosting.vfs.tests -u

Also, I don't understand the difference between -m and -p, given that
you pass a package to -m... oh, it seems that -m takes a regexp whereas
-p takes a package path.  That suggests that -p ought to be fractionally
faster, but it really doesn't seem to make any difference to me.

In any case, yeah, don't use -t if you can get away without it!
