It sound like the exact same symptoms I have noticed with Firefox:
-No effect on memory
-All actions eventually done, but very slowly so
-Slow-down is gradual, but nearly a /halt/ is reached rather quickly (within
seconds), which then exacerbates significantly.

I would have to doubt it. I always have my system monitor at the top and
jusdging by the memory bar, there is no leak. No memory appears to have
leaked in nearly a month of uptime with heavy Firefox use.

Good suggestion. I think it might be easier to avoid continuous mouse
pressing (see below).

The above appears to make sense to me, _but_...
Undo should not keep track of continuous strokes. Once a stroke is undone,
it is undone entirely[1]. This, in fact, is why I often prefer many small
stroke to one persistent stroke -- the undo stack. There are exceptions,
however, e.g.:
- fuzzy selections where letting the button go immediately leads to a
selection being made.
- Bezier curves and the like.

the menus have me disorientated)
