Threads, sound etc

Hello,

I’ve written a lightshow-like app, that records sound and draw graphics
accordingly. I’ve almost finished the SDL port aiming at portability beyond
linux (and svgalib - my first go).

Is sound recording going to be supported in SDL? Right now I have to use OSS,
which is kind of defeating the purpose of portability.

And another thing: when the app exits normally, it leaks behind a sysv-ipc
semaphore. Is this normal, or am I doing something wrong?

Thanks
Nikos
