As part of #27426, I build test binaries and ran bincheck (simply stick test:27426 in the VERSION file).
It failed while running the windows binary with:

C:/projects/bincheck/mnt/cockroach.exe: error while loading shared libraries: libwinpthread-1.dll: cannot open shared object file: No such file or directory

Since it didn't seem related to my change, I retried with the most recently-merged PR (#27422). Same failure.

@benesch: I can try other PRs but it's a little slow to iterate. Any ideas? I'm going to try pre-rocksdb bump first.
