[svn-r11904] Purpose:
Add a file that I forgot in my last checkin. Description: t_cache.c is the source file for the new parallel metadata cache test. Solution: See above. Platforms tested: h5committested before the last checkin. Will run another h5committest shortly, but it shouldn't be necessary as there are no new changes. Misc. update:
