Ok, this sounds like this leak is at least a large part of that.  Assuming
the average URL length is 40 bytes, that version would leak 26MB in 24
hours, according to the stats you give.  If requested URLs are much longer
(e.g. due to forms using request method GET), it may well account for all of
it.

This strongly suggests the leak is in a C module somewhere, which is
consistent with the _c_urlarg bug.
