too many to list, really. It's more than 60 separate patches that went
into 2.5 in the past 2 months that implement all the necessery
infrastructure for NPTL-style 1:1 threading. Futexes had to be fixed too,
so it's not like you could use the existing 2.4 futex patch for NPTL. I'll
attempt a 2.4 backport of all the threading bits within the next couple of
weeks, but it's not a matter of a couple of hours ...

but, 2.5 isnt all that bad these days, and Arjan is currently working on
2.5 kernel rpms, to make it even easier to try out. (it will be announced
to phil-list once he's done.)
