bug in qlim + qmetro ?

Hi, I noticed this the other week while working on something, maybe
I'm missing something, maybe not.

When driving a qlim with a [qmetro 2], it sends out a double bang.
[metro 2] does not produce this behavior.

Reproduction is straightforward : [qmetro 2] - [qlim 6000] - [print]
Example patch below.

I would expect this to send a single bang once every six seconds, but
instead it bangs 2x.

I've noticed this in Max 4.6.2 version under XP SP2 and OSX 10.4.8
(Intel), running on a MacbookPro 2Ghz.

Sample patch below :

Am I crackers seeing this?

Thanks,
