@bcmills requested issue #58933 to be considered for backport to the next 1.21 minor release.

@gopherbot, please backport to Go 1.21. This was a use-after-free bug and could cause arbitrary heap corruption in programs that call SetFileInformationByHandle, and it also produces nondeterministic test failures on the release-branch.go1.21 builders.
