Ah, yes, and I am running... (drumroll)
Windows 2003!
Thanks. Then I need to implement my functionality the
hard way.

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.
