gcc git locked out for hours second day in a row

[Jakub Jelinek]

Hi!

Yesterday the gcc git repository was locked for 3 hours
locked by user mikael at 2024-06-11 13:27:44.301067 (pid = 974167)
78:06 python hooks/update.py refs/users/mikael/tags/fortran-dev_merges/r10-1545 0000000000000000000000000000000000000000 c2f9fe1d8111b9671bf0aa8362446516fd942f1d
process until overseers killed it but today we have the same
situation for 3 ours and counting again:
locked by user mikael at 2024-06-12 08:35:48.137564 (pid = 2219652)
78:06 python hooks/update.py refs/users/mikael/tags/toto 0000000000000000000000000000000000000000 cca005166dba2cefeb51afac3ea629b3972acea3

It is possible we have some bug in the git hook scripts, but it would
be helpful trying to understand what exactly you're trying to commit
and why nobody else (at least to my knowledge) has similarly stuck commits.

The effect is that nobody can push anything else to gcc git repo
for hours.
