Actually, perfmon produces quoted column output, tab separated (tsv).  
Thus, each header is enclosed in quotes, and each value is encapsulated 
in quotes.  So, commas as mantissa/<uhh..number> separators shouldn't 
cause a problem in parsing the fields.

Ick.  The script that translates perfmon files into regular orca files 
sounds more useful every email I read.  Although it'll be annoying to 
have to re-run that script on old data whenever it needs to be 
processed.  There might be a way to pipeline that ..

Yay.  I've already seen some weird ones from 3Com, but winallator seems 
to handle it okay the first time 'round.  Second time is not so fun, 
though -- blowing away the HTML directory fixes it.  I'm tempted to 
track down what's causing it, and post it as a patch, but I bet the 
winallator guys are way ahead of me. :)
