On windows 2000 platform, a lot of NSK tests failed with following message.
"java.io.IOException: shmemBase_listen failed: Cannot create a file when that file already exists"

This occur with server VM only, it passed with client VM. It also passed with
server VM in int mode.

Here is how to reproduce the failure:
1. MAP \\vmsqe.sfbay.sun.com\export to Y: (on windows 2000 machine)
2. cd y:/Bugs/4905551
3. ksh run.ksh [Location to your java] [vmopts for debugger]
Example:
ksh run.ksh y:/pit/tiger/JDK/b13/win/bin/java -server -Xmixed
