I tried running it on Fedora 37 x86-64 on a slow machine (AMD Phenom II 
X4 910e) and reproduced the timing bug. The output of 'make check' 
contained:

    GEN      lisp/server-tests.log
  Running 7 tests (2023-02-23 09:45:51-0800, selector `(not (or (tag 
:expensive-test) (tag :unstable) (tag :nativecomp)))')
  make[3]: *** [Makefile:174: lisp/server-tests.log] Error 157

I guess "Error 157" means signal 29 (157 - 128), which is SIGIO on this 
platform.

This was with Emacs master (commit 
6411a9af03a4eb1a82db47a9642b11ba7edaaaf0).
