Have you checked out Smalltalk MT (either of you?).

"""Robust multithreaded implementation: Smalltalk MT is multithreaded from
the ground up, with garbage collection running in a separate thread. A
process can have any number of threads. This enables the development of
scalable applications on Windows NT, and simplifies considerably the
design and implementation of applications that use blocking I/O. There are
no restrictions on sharing data between threads (other than
application-specific synchronization issues). In addition, all Win32
synchronization mechanisms can be used, which enables a non-Smalltalk
thread or process to synchronize with a Smalltalk thread. Starting with
version 2.5, fibers and asynchronous procedure calls (APC) are also
supported. """

I've heard *lots* of praise for them. To my mind, if one is looking for OS
thread support in a Smalltalk, here is the place to look first.
