After the update from 36d6e65722e to f2400e6e832 I noticed build of
some ports hang up in the middle of it on my 14-CURRENT amd64 host.

One of such examples is security/py-cryptography.

And another one is devel/arcanist-lib.

The problem also happens with poudriere.

I tried boot with old 36d6e65722e kernel but the problem still
happens. So the cause may be older than it.

Does anyone else have the same problem?

Best Regards.
