The cprofilev tool in the OP also allows drilling down; the default view
shows all levels, but by clicking on function names there is a drill-down
that shows how many times function X is called, and also what it calls.
Repeat drilling to get further in.
(I missed something in trying to set up runsnake in a virtenv; "import wx"
kept failing, so I can't compare the tools, but the sample picture on the
site was intriguing.)
BTW: a read() such as in socket.read() is hardly something that needs fixing

I gather that identifying painful queries is of value, and either figuring
out how to do them less often or rewriting the query to be less painful,
but my stuff is much to simple for me to have gotten into that yet.
