No, nore will it ever be multi-threaded in a sence that it controls its own
threads. It will be thread safe and reentrant for multi threaded servers.

However, I do beleive I remember reading that in some instances odbc will
create new threads to handle certain stuff (and certainly some other stuff
as well), so there may be parts of php outside of our control that spin off
other threads. This shouldnt cause any problem, as those threads should
never enter back into php code.

shouldnt be necessary. I have php on nt with iis4 in a live environment,
and don't have this problem...yet. But anyway, the server modules will
handle this much more effectivly. The problem is being able to consistently
recreate the problem on demand, then to isolate what php is doing in that
instance. I've not been able to make the 'hangup' happen when I try to do
it, so I havent been able to figure out how to fix it.

always thought asp was an isapi module. Oh yeah, they changed it in iis4 to
make it harder for others to integrate it with non-m$ servers.

What do you mean by 'thinner'? Anyway, PHP 3.1 code is available in cvs,
and I have made pre-alpha binaries available, of working isapi and apache
modules. The code is open to be worked on :)
