Re: svn commit: r37363 - in trunk/subversion: libsvn_ra tests/cmdline

From: David Glasser <glasser_at_davidglasser.net>

You shouldn't be writing authz files inside merge_tests.py; use
merge_tests_authz.py instead. Unless something's changed while I
wasn't paying attention, authz-based tests aren't safe for parallel
execution, and merge_tests_authz explicitly disables parallelism.
