The last time I checked, there was going to be a separate AIX version
for 4.2 only which used the native threading interfaces. However I've 
looked on the 2.01 download pages and there only seems to be one AIX
entry.

If you haven't already and you're interested in a server which does 
this (it would probably be more stable and easier to code with because 
you would be able to make blocking system calls) you should check with
tech support or the devlopers program to see if they know where you can
get it. In the meantime I will ask around.
