Subject: Re: ioreplay allows replaying fs traces from a strace log file

I played around with this about a month back during a rados bench run, 
but had some trouble getting it to work when strace was attached to an 
already running process.  I didn't end up spending a lot of time on it 
though.  Jeff Layton also wrote a strace analyzer tool specifically for 
IO, but it needs a bit of work to support -f.  His stuff can be found here:
