vchoi_fork

[svn-r11772] Purpose:
Feature

Description:
Added posix compliance tests.

Solution:
These tests do increasingly complicated sets of writes followed by reads.
POSIX standards say that any read that can be proven to occur after a write
must include the data in that write.  These tests attempt to verify whether the
underlying filesystem and i/o layer provide such guarantees.


Platforms tested:
copper, colonelk, red storm
