running mac os 10.4, and the latest version of vanilla pd with -nogui, the attached patch does not work how it should. 

the patch is a simple phasor~ ping sound, run through a [delread~] / [delwrite~] delayline.  with gui turned on, it works as expected, making a feedback echo,

but with -the nogui option enabled, the delayline is just making a small delay (my guess is one block)

is this a known issue?  are there other known issues with running -nogui on mac, or in general?  this is the first definite trouble we have isolated, but i think we might have some other issues too.
