[PD] tried but cannot sync A/D/A if I try to set delay>50

If I go to media/audio setting and try to set a delay higher than 50ms, 
I get a lot of "tried but couldn't sync A/D/A" messages and then "audio 
I/O stuck... closing".

This is on Ubuntu 10.04 with Pd Extended 0.42.5, with ALSA.

In windows I used to increase the delay when I had cpu-heavy patches (or 
when some other cpu-heavy application had to run on the same computer) 
in order to have a bigger buffer and less dropouts and it used to work 
seamlessly. I got more latency, obviously, but it worked better (less 
dropouts), not worse.

Why do I get these errors, what do they mean and why should a higher 
delay value trigger them???
