the xgap package was the guilty party causing trouble if my memory
serves me right from all those years ago. It was automatically loaded too.
I cannot remember how I figured it out now. xgap would not load by
itself these days, if it still exists.

I have opened https://github.com/sagemath/sage/pull/39783. The
immediate goal is to add a recent gap package. There are several
points tangentially related with this PR that I wanted to share to the
community:
1. Is there a reason to do not add some other packages? Long time
ago, I think someone told me that they may interfere with other
sage packages, but it is not clear to me since they must be loaded
explicitely.
2. The compilation of gap_packages takes quite a while. Taking out
sdh_make -j1 in spkg-install.in allows to compile in parallel each
packages, but I wonder if there was a reason to avoid parallelism.
In the same ideas, since there are several packages to be built,
it could be a good idea to allow parallelism at the level of
packages, but I do not how to do it.
3. The third one is related with the use of gap functions. One option
is to add more functions to gap_functions.py, but I do not know if
adding too much functions may affect to the memory. A second
option is to use libgap.function_factory; it is OK. My issue is
how to pass options to gap functions. I have not found how to do
it. In order to use libgap.eval, I do not know for example how to
produce a gap string from a sage group.
Thanks, Enrique.
