After building ports for 1day, 23hours and a couple minutes, all successful completion, finally the build fails with ZFS deadlock:
No disk errors, no memory errors, just one of those places in ZFS where something has been forgotten to cleanup.
Scrub is still fine, the git process is obviousely unkillable and the filesystem cannot umount.
