Phil, I wonder how this slipped through.. sigh. I am really terrible at applying patches :( I will try to investigate the ncache issues with the mpi program later today. But how about adding mount options (and parsing code in pvfs2) in the pvfs2tab file like "noacache, noncache" to disable per-fs m

Hey gang One of the ROMIO tests (noncontig_coll2) started failing around the time we comitted the revamped ncache. If I disable the ncache by setting NCACHE_DEFAULT_TIMEOUT_MSECS to zero, the test passes again. Sam and I have a couple solutions, but none of them are satsifying given we need to c
