Migration threads

[Richard Braun]

Hello.

>From what I understand of the Hurd history, GNU Mach is based on Mach 4.
I read that this version was intended to include the result of research
work made at the university of Utah, the most important being thread
migration (for those not familiar with the concept, it means that
threads running in client tasks "migrate" into server tasks when
performing sync RPC). There is actually code about that in GNU Mach,
but I'm wondering if it's actually used in the Hurd. I couldn't find
anything related to this in the userspace servers, but the interface
change could be light, and I might have missed them. Does anyone know if
the Hurd servers actually use thread migration ?
