Short answer: Not out of the box.

You're going to have to simulate concurrency using multiple threads, just
as the browser does to eliminate the serial nature of the playback.

You can reasonably assume that if you have enough threads all playing back
the same recording in multiple different sessions there will be concurrent
requests for the resources, but across multiple sessions rather than within
a single session. This is not perfectly realistic, but probably will be
good enough for most testing purposes.

If you really need the same session to generate concurrent requests then it
is a bit more complex. You'll likely need to split the recording into
concurrent sub-recordings that can be executed across concurrent Grinder
threads using something like
http://grinder.sourceforge.net/g3/script-gallery.html#parallel.py. Any
shared state (i.e. the session id) will need to be passed to all the
Grinder threads that are running the sub-recordings.

Hope that helps,
Gary
