Mike and Jan,
Thanks a lot for your responses!

*Mike*,
What I understand from your explanation is
1. The virtual size shown by 'top' and 'pmap' doesn't mean that my
application is eating up much space in the physical memory.
2. I can safely ignore this memory usage shown.
Please correct me if I'm wrong.
Now, how can I confirm this? My point is, is there any utility to measure
the physical ram usage?

*Jan*,
I could not find a reference to g_thread_create_full anywhere in the
gstreamer core. Instead, it is there in some files in glib source. In all
places, the stack_size is being passed as 0 (highlighted in the below pasted
log).
Can you please tell me if I'm looking at the right places?
thanks again,
gireesh
