Comment(by afarmer):

 Sorry for the delay. Here is the patch with the seq inside the return, as
 recommended by ezyang. This is confirmed to fix the leak (in conjunction
 with the first patch you already merged) in our HERMIT use cases.

 I'm working on a minimal performance test for the testsuite... I'll post
 here when I have something.
