Comment (by davidsarah):

 Subject to fragmentation issues, CPython does return memory to the OS:
 [http://bugs.python.org/issue1123430]. I tried to test whether uploading a
 second file resulted in the same additional memory usage (suggesting a
 leak) or less (suggesting that not returning memory is part of the
 problem), but couldn't complete the test because my machine became
 unresponsive. I'll try again when I have more free memory.

 Note that it's RSS that we're measuring, not virtual memory. Memory
 ''pages'' that aren't being used shouldn't be counted in RSS (eventually).
