[Sbcl-devel] Fwd: Re: Request for review of Windows threads support

[<ra...@ra...>]

Not having ever written to this list, I hadn't realized that I was not replying to the list. Sorry. 

As for a request for Windows API chops, I've got those, it's the SBCL internal knowledge I'm missing (and little pthreads knowledge).

I tried it, and it didn't work for me, but I was doing something 
somewhat unusual. 

I was trying to write a CFFI for portaudio. Portaudio on Windows uses 
CreateThread, and uses that thread for callbacks to fill the audio 
buffers. 

I didn't do much tracking, but calling back into your version of a 
threaded Windows SBCL from an externally created thread was pretty 
unstable. It might work a couple times, then crash. Or it might crash 
the first time. 

Sometimes, I might get to run my function a few more times by 
initializing portaudio twice before calling anything else, which is 
pretty weird behavior.
