[PD] number boxes and GOP under Windows

Has anyone noticed some nasty performance issues over time running patches 
with number boxes and GOP?

Number boxes seem to affect performance proportionately to how many times 
they've changed. Leaving a patch open that has multiple number boxes that 
change a few times every second (for example bars:beats:ticks timer) for an 
hour or more can sometimes bring my system to a grinding halt. Restarting 
PD and reloading the patch usually fixes it.

This seems to exacerbated if the number boxes are within a GOP canvas, and 
even more so if said GOP canvas is contained in another GOP canvas (for 
example, a GOP VU inside a GOP preamp).

My immediate guess is that the number box code is doing dynamic memory 
allocation, and fragmenting memory over time. Is this a PD thing or a 
tcl/tk thing?
