If the memory is not freed when you close the player then
it
usually means that the leak is not in that executable. The
operating system should reclaim all memory once an
executable
exits. Could some of this memory usage be local disk space?

I am not sure, I do not work on WinCE.

Also, take a look at the following defines and see if
they are using in filesystem/http on your branch:

project.AddDefines('HELIX_FEATURE_HTTPFSYS_MEM_GROWTH_LIMIT'
)
project.AddDefines("CHUNK_RES_MEM_FLOOR=128000")
project.AddDefines("CHUNK_RES_MEM_CEILING=256000")


If so, setting theses in your profile might help.
