=09Yes, I know linux threading sucks. However, apparently
=09all that kludging inside HotSpot works obviously quite
=09well under Linux. The problem here is that people think

=09I think that most of us would like to help you, but I have understood
=09that this is very difficult and complex area to work with. Please try =
to=20
=09continue your work - if you don't make it looks like that=20
=09FreeBSD HotSpot support won't been seen in hear future
=09(at least I haven't heard anyone else working on that)

=09=09Ari S.
