Hang in 'checking cached actions'

[peakschris]

Description of the bug:

I've not got a reliable way to reproduce this yet, but I've been seeing Bazel 7.1 hang during 'checking cached actions', on a 16-core Windows machine. This is quite new. The thing I've changed recently is to write a 'warm commit builder' that, in a loop, checks out latest commit, builds it, then moves onto next. Each new checkout probably changes only 100 files in the source directory. The hang happens every 10 or so builds, and might last 5-20 minutes before it continues. I've reverted to bazel 7.0.1 for now, and will monitor.

Has anyone else seen this recently?
