Depending on your user rights you might be unable to access the POSIX
process information object created by Cygwin processes running in
another session.  This is a result of a change starting with Windows
2003 and XP 64 bit.  The current solution in Cygwin is slighlty
incorrect but we don't have a nice workaround so far.
