This is the first part of #3121, which is correct even though it failed at its intended objective to fix #3119.
This PR just ensures that the
queue
and thepool
are cleanly set to zero,so that no uninitialized noise can influence the behavior.
These memory areas are small, and employed in a context of much higher load (multi-threading, context-switching, etc.),
so there is no expectation of performance impact.
It just turns out that #3119 is more likely triggered by a race condition than a side effect of uninitialization.
Yet, the patch looks useful, as it removes a potential source of random issue considered during the investigation for #3119.
