Is that the syntax - I can try it and see what I get.

Good - you can explain Cygwin PIDs to me.  When I run one of the osg examples 
from a bash prompt in Cygwin it appears the PID I am seeing does not always 
match the PID that Windows Task Manager is showing.  I actually have my 
Cygwin set up so it passes through login.exe before starting bash.exe and you 
never see the pid for bash shell but instead see the entry for Bash with  a 
pid that belongs to the Login process so it becomes difficult to know where 
to attach.

For OSG - no,  but I do like using X for some things and just to experiment.
