[gst-devel] memory usage on a small gstreamer application

i created a small gstreamer application.  it creates a pipeline, two
filesrc elements, 1 fakeadder element (same as adder), and 1 fakesink
element.  each filesrc element reads from a file and sends the
information down the pipeline to the fakeadder.  the fakeadder does no
processing and just pushes it to the fakesink.  the data is then
displayed to the console.

i put a sleep in the code right after all this processing and before the
pipeline is destroyed.

the application is dynamically linked and is running on a mips processor
with a 32M flash part and a 64M DDR RAM part.  montavista linux is the
operating system and the root filesystem is nfs mounted.

to get the following memory numbers, i did a cat on the proc filesystem.
would anyone like to comment on the memory numbers?  i realize the
memory numbers are virtual numbers but seems like quite a bit of memory
for such a small application or is this typical?
