[vorbis-dev] Parallelism

[Chris Hanson]

I think a better solution to parallelism is to just make sure the 
library is reentrant and let developers implement parallelism at a 
higher level.

If you desperately want some sort of portable parallelism within the 
implementation, I suggest wrapping it up in an abstraction layer 
which can use POSIX threads, MPI, or the native threading interfaces 
on Windows and Macintosh.

Another suggestion:  Be careful what you do in the threads.  MacOS in 
particular has restrictions on what threads can and cannot do.  For 
instance, a preemptive Multiprocessing Services thread can only make 
certain types of File Manager and Multiprocessing Services calls; I 
don't even think it can allocate memory.
