x/build, runtime: Windows arm64 builder fail to allocate memory

[qmuntal]

The gotip-windows-arm64 bots were updated yesterday afternoon, and since then all CI runs fail because VirtualAlloc returns ERROR_COMMITMENT_LIMIT. See for example https://ci.chromium.org/ui/p/golang/builders/ci/gotip-windows-arm64/b8718210226708771345/test-results?sortby=&groupby=.

This is probably a configuration issue, although maybe rebooting the boot also solve it. Don't have permissions to do that myself. @dmitshur

Indeed. Thanks for filing this issue and de-duplicating all the related watchflakes reports.

The "yesterday afternoon" update was likely an automated one rather than something we did manually.

I've restarted both builders, and they seem to be back to working okay. We still have #66962 open that tracks the occasional problems with the builder, though they seem to have been much more stable in the recent months, and this is one instance when they weren't. Closing this.
