buffer~ object inconsistency

Hello

I've noticed a quirk in the buffer~ object. Steps to reproduce:

1. open patch below
2. load 22KHz audio file

Expected behaviour: buffer~ remains 1000 ms long, 1000 ms of audio
gets loaded in

Actual behaviour: buffer~ gets resized to 2000 ms long, only 1000 ms
of audio gets loaded in, last 1000 ms of buffer is empty.

Desired behaviour: buffer~ should always stay length defined by its
argument, unless replace or size messages are used, even when
soundfiles using different sample rates are loaded.

Version info: MaxMSP 4.5.5, MacOSX 10.3.9

Now I can probably guess WHY this happens, but that doesn't mean I
LIKE that it happens :-P

Or am I being too finicky?

bless the little C74 elves.
