[PD] file access audio glitches

Hi everybody,

I'm not even certain this is a problem across all operating and sound 
systems; it certainly is a problem on my setup with OS X.  Any sort of 
file access has the possibility (*probability* on the first access to a 
given file) of causing audio dropouts.  For instance, if I use [tunetof] 
to load in new scale data, the first time I access a given scale file, 
there's a dropout.  Subsequent accesses of that same file don't seem to 
cause dropouts.

I currently just switched to PD 0.40.3-extended, but this has been 
happening for as long as I can remember -- several versions back.
Is this behavior common across PD, or just something intrinsic to OS X 
or my sound hardware?

Also, is it some kind of file caching that's keeping subsequent access 
to a file from causing dropouts?
