A long description of the two competing problems is in the bug report (one old, one recently introduced trying to fix the old one). In short: buffer data during socket._fileobject.read() and readlines() within a cStringIO object instead of a [] of str()s returned from the recv() call. This prevents excessive memory use due to the size parameter being passed to recv() being grossly larger than the actual size of the data returned *and* prevents excessive cpu usage due to looping in python calling recv() with a very tiny size value if min() is used as the previous memory-use bug "fix" did. It also documents what the socket._fileobject._rbufsize member is actually used for. This is a candidate for back porting to 2.5. ................ r62636 | mark.hammond | 2008-05-02 14:48:15 +0200 (Fri, 02 May 2008) | 2 lines #2581: Vista UAC/elevation support for bdist_wininst ................ r62638 | facundo.batista | 2008-05-02 19:39:00 +0200 (Fri, 02 May 2008) | 3 lines Fixed some test structures.
