Can the Gradient tool be made interruptable, e.g. user can hit Escape to cancel the process from mid-fill?

I frequently use linear gradients of late for background effects in GIMP, and have started using them latest on my high-resolution (150dpi) images instead of the web-sized (75dpi) versions I later upload to my online gallery pages.  Naturally, a gradient fill across a 2.1+ magapixel image will require some serious CPU time, especially for one running at 800MHz.

I've experienced several occasions where, intending to apply a simple Linear gradient across the background, I forget to review the Gradient options before creating the fill, and the cost of that mistake seems to be to the tune of a Darken Only, 80% opacity clockwise-spiral reversed gradient with a triangle-wave repeat pattern, in other words very computationally expensive.

(I can't remember the last time I used anything close to such arcane settings for a fill -- but that's not the point.)

If a computationally expensive tool like the gradient-fill can be made interruptable, e.g. hit Escape to abort the operation, so that I don't have to wait for the tool to finish just so I can "Undo" whatever happened and try again with the correct tool settings, this would save me considerable time when a small oversight like this happens (because small oversights, althouh rare, always have a way of happening anyway.)

In the meantime I've reviewed the options on all GIMP's tools, saved them to disk manually, and am hoping it doesn't happen again.
