Comment (by zooko):
"each time this happens, the memory usage goes up a bit - even though even
last bit of the history will get discarded once the page has been
constructed and sent off to the client. (We've checked for memory leaks"
If the memory usage continues to grow when a substantially similar task is
being performed over and over, then this is a memory leak. That's a
separate issue from returning memory to the OS. Personally I don't think
returning memory to the OS is worth the effort. The OS will swap it out
anyway when it is unused. (Hint: never look at the "virtual memory size"
on linux. It is a useless and misleading number -- it doesn't correlate
with anything that we actually care about.)
