I'm currently suspicious of the implementation of signal delivery and return handling for unrelated reasons. It is possible that its also affecting this. I'm trying to diagnose/fix an i386 binary problem and it looks like something might be missing in the MD code thats needed for interaction with KSE, or something could be wrong with the ERESTART handling. Anyway, I'll look into this again. BTW; can somebody point me to a .ogg file I can test with? BTW2: the last time I asked for a .ogg file, I got sent a livejournal recording from one of the committers' sisters.. it was very scary. :-) -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5
