Ok John. I will work on the changes you suggested in the next
days and send you the user level tools patch.

Right now we don't need the escape codes. Those are used for
supporting
delivery of passive domain samples, ie. including an event sample from
a domain without oprofile to another domain that has oprofile running.
The escape codes are used to indicate a sample belongs to a different
domain. The current version does not support passive domains, so we
really don't need the escape codes at the moment. I am planning to
change the
way passive samples are handled, so we won't need escape code for that
either, but this will require some more time (I am planning to use
separate buffers for different domains, but I will have to discuss
this
in more detail with you later). Would you be happy if for now I
remove
the escape code completely? This should be easy to do.
Thanks for your support
Renato
