1747273 - Ignore the GC interrupt flag if the GC goes on for too long

Status: RESOLVED FIXED

(Core :: JavaScript: GC, enhancement, P1)

Description

[Steve Fink [:sfink] [:s:]]

Bug 1672121 introduces the risk of a GC getting constantly interrupted and being unable to finish an incremental collection. CCGCScheduler::ComputeInterSliceGCBudget will try to start lengthening the slices, but they're still interruptible. Eventually, the GC will take long enough that it will be finished non-incrementally.

It would be safer if the interrupt flag started getting ignored at some point, perhaps at the same time the slices start getting stretched?
