Ask on SuperUser *NOT* SO!

Cygwin exposes these MS Windows Executive Object Manager subsystem resource 
objects under /proc/sys/ and object namespaces are per session under 
/proc/sys/Sessions/ you have e.g.

$ ls -glo /proc/sys/Sessions/BNOLINKS/
total 0
lr--r--r-- 1 0 Apr 19 21:23 0 -> /proc/sys/BaseNamedObjects
lr--r--r-- 1 0 Apr 19 21:23 1 -> /proc/sys/Sessions/1/BaseNamedObjects

so each session has its own set of BaseNamedObjects, which you can list with 
appropriate permissions, or using a tree browser.

Under MS Windows you can use Sysinternals WinObj64 to browse the hierarchy and 
objects.
