Hrm, the problem with these events is that they are more "high rate"
than medium rate by definition. Also, LTTV should have the necessary
information in the fork() event to map the pid.

I can take a closer look to the trace. Can you create a .tar.bz2 file of
it and give me (in private) an url where I can upload it ? Or tell me if
you prefer some other transfer mechanism.

You could also give me a sample case where it does not work : is it in
the GUI ? in textdump ?
