[svn-r12705] Description:
Fix file handle destroy routine to not attempt to flush out partially
initialized file handles (when opening a file fails).
Tested on: (until they finished testing, this time... :-)
FreeBSD/32 4.11 (sleipnir) w/threadsafe
Linux/64 2.4 (mir) w/1.6 compat
Linux/32 2.4 (heping) w/FORTRAN & C++
