you can turn off threads and processes to aid debugging:
https://code.google.com/p/modwsgi/wiki/ProcessesAndThreading
StartServers 1
ServerLimit 1
With this configuration, only one process will be started, with
no additional processes ever being created. The WSGI
environment key/value pairs indicating how processes and
threads are being used will for this configuration be as
follows.
wsgi.multithread False
wsgi.multiprocess False
In effect, this configuration has the result of serialising all
requests through a single process. This will allow an
interactive browser based debugger to be used, but may prevent
more complex WSGI applications which make use of AJAX
techniques from working. This could occur where a web page
initiates a sequence of AJAX requests and expects later
requests to be able to complete while a response for an initial
request is still pending. In other words, problems may occur
where requests overlap, as subsequent requests will not be able
to be executed until the initial request has completed.

did you try tracking init state in your library and have entry
points call D runtime if not already initialized?
Thanks. I'll use that information about WSGI to test whether it
really is a thread/process issue. Multiple requests causing
re-entry definitely isn't the problem yet but worth being wary of
down the road. Also intrigued by the idea of using a
browser-based debugger.
I tried a variety of combinations of initialize and terminate but
not specifically calling initialize from the request thread only
once and without calling terminate. I'll give that a go but I'm
no too hopeful as initialize/terminate pairs don't work,
initialize from the start-up thread doesn't work and the docs are
unclear whether initialize doesn't already do said state checking
for me.
