GsFile operations can hang on seteuid / __nptl_setxid GLIBC bug

Customers running Linux GLIBC versions prior to 2.12 may be subject to a GLIBC bug (bug 3270) which can cause GsFile operations calling the OS seteuid( ) operation to deadlock.  Using pstack to view the stack of the hanging gem, if you see these entries then you may have hit this bug:

     __nptl_setxid () from /lib64/libpthread.so.0
     seteuid () from /lib64/libc.so.6

Workaround

Upgrade your Linux machine to use a newer version of GLIBC.  You should upgrade to version 2.12 or later.
