Ah.  Well, that certainly finesses all the issues.

Not surprised.  Particularly as it all seems so badly defined :-(

For my application I would be happy to have a mechanism to give some
higher priority to the I/O driven threads, and to lower the priority
of the garbage collector and scanning threads.  The higher priority
stuff ought to be system scope, the lower could be process scope.  The
POSIX defined stuff almost but not quite provides that, but is so full
of implementation-defined and not defined at all, that it seems quite
useless to me.

Thanks,

Chris
