Tests in Max that stand out:
Reading and writing coll files while sound is running does not cause xruns in Max, whereas in Pd it can depending on the size of the coll file and CPU utilization.
yes, I've checked that too... Max never chokes on the audio processing.
You are right in that determinacy is preserved in Max no matter what (e.g. read outlet bang outputs immediately after issuing the read message in logical time).
See, always confusing to me when determinacy is mentioned... that's not how it happens in Max if I understand it... In Max it takes a while (until the file read is ready) for the outlet to send a bang, it doesn;t go out
"immediately" as in the unthreaded version in cyclone, where it causes audio drop outs
Doing Uzi with 100k generated entries into coll object in Max and I get guaranteed crashes from these on both 6 and 7.
well, I tested opening a file with 300k entries in Max 7 and got no audio crash/choke... it loaded the file fine, taking a bit under 500ms and the audio wasn't interrupted. I also had a block size of 1 and audio I/O of 32 samples, highest CPU consuming setting possible, it was around 13%

I was also sending the file attached, but that's why my message got rejected...
