[PD] Jack and PD plus another question

[Miller Puckette]

This is my understanding as well...  :)  I tried to make Pd into a true
callback application a few months ago, only to discover that it made no real
improvement in the APIs that ewre supported then.  If it turns out that
pd/jack actually performs better using true callbacks I might reconsider
and make the change.

Putting audio in callback routines in Windows seems to be out of the question
since callback routines can't make system calls in windows.

cheers
