[CVS commit program]

Update of /projects/cvsroot/pvfs2/src/common/misc
In directory parlweb:/tmp/cvs-serv16386/src/common/misc

Modified Files:
	pvfs2-util.c 
Log Message:
- for non-blocking the passed in sys_attr structures need to be copied
  to avoid stack corruption/bunk values (similar to credential problem;
  there are probably more instances just like this, and they'll be fixed
  as they come)
