If you are, can you confirm that it's actually hanging, and not just
slow? On my system, test 26 takes about a minute to run (which is why we
don't do it by default).

Nearly sure. After 10 minutes, the test was still running.

Yesterday another machine was running even longer.

Any tips, how to debug, are welcome.

Try running with "-x" to see what the test is doing. It will probably be
in:

   + git -C too-many-refs fetch -q --tags

after a while. Check "ps" to see if you have a fetch-pack sub-process
running. It should be writing "have" lines and reading lots of ACK
lines, which you can check via strace.

If it's blocked on read() or write(), then it's probably some kind of
I/O deadlock.
