Experience gained from listening to music while programming in cafis :
iTunes consistently drops out for me when Codewarrior writes a
binary to disk. This is on a Pismo with 192Mb, so perhaps it is
paging iTunes out briefly in which case that says nothing about the
threading. In general Codewarrior seems to hog the processor though.
The machine's responsiveness drops to near zero during a heavy
optimize, but iTunes still plays. It only drops out when Codewarrior
writes a binary to disk.
Another problem is that system beeps nearly always glitch for me.
Probably a problem of trying to play while simultaneously being
paged back in.

Have you tried this with the audio files on a separate disk? It
could also be that CW is consuming most of the available disk
bandwidth (it's probably queuing huge transfers when it writes out
the binary).
SOP for critical audio work has always involved using a separate
spindle for the audio data. If OS X had real-time queuing for disk
I/O, one might not need separate disk, but OS X doesn't have that and
disks are cheap...
