Matt Glazar 40b5223d24 Work around system-wide hangs: disable process name cache 
Summary:
Some people encounter system-wide hangs on their Linux machines. Debugging points to a deadlock related to EdenFS' process name lookup code. Disable the process name cache during FUSE dispatch to avoid the deadlock.

Effects:

* Hopefully, the deadlock no longer happens.
* 'eden top' will no longer report process names. (It should work otherwise, though.)
