among the things we have to take care of:
- signals: signal, in current implementation, is sent to a thread. in 
nptl, it's sent to the process. So, lots of thread control has to be 
rewritten
- in the same type of issues, getpid() now returns the same pid for all 
threads in a same process. Most of Wine code relies on having a 
different pid for each thread (this fix is needed, IIRC, for some 
Solaris port)

from what I've seen, the LDT/GDT with nptl should be easier:
- for Win32 processes, as Ulrich already wrote, we could got rid of LDT 
(and only rely on GDT) for %fs and TEB allocation
- for Win16 processes, we would still require LDT sharing across 
pthreads, which I don't how it's handled right now

and it's likely there are quite a few other items I forgot

A+
