Yes, that's pretty weird. The only writes to "OUTPUT" are relative to
emacs default-directory. Not sure how that could be set to /usr/bin;
possible some weird script involved with starting emacs?

One thing that might help is to make the wait some global variable
amount of time, and
various CI/build scenarios could set it to some generous length.

there are some very slow architectures (e.g. mipsel) on the debian
buildds, so I'm a bit surprised we don't see similar issues there.
Maybe you are just doing more builds (which is great, obviously).
