pydb (http://bashdb.sf.net0 has the ability to do noninteractive line
tracing.  See http://bashdb.sourceforge.net/pydb/pydb/lib/subsubsection-set.html
or the showmedo demo. It would be kind of neat to extend this to allow
for method/fn tracing. Alas the simple hack I tried, didn't work
because of code obscurities. (The code could stand to use a rewrite.)
