> Big there's still the obvious question: what is that `gap` process doing
and why does it keep running for a while?
that it's the same GAP process as the one that gets started during the
"normal" Sage startup.
And it does the following things, as you can see by uncommenting
{{{LogTo}}} line at the end of {{{sage.g}}}.
{{{
gap> LoadPackage("ctbllib");
true
...
gap>
SaveWorkspace("/var/folders/qW/qWY+4Ku1GF0WXrOsV+IDvk+++TM/-Tmp-//dotsageKTXveD/gap/workspace-8046660130267724445");
true
gap>
}}}
{{{LoadPackage()}}} things are OK, it's just loading GAP's packages.
The tough thing is {{{SaveWorkspace()}}}, which dumps GAP's workspace into
a binary file; which can be loaded back --- well, not in this case of
course, cause we are invoked with --nodotsage, so it goes to waste.
So I suppose that's what gets stuck, and crashes, for some reason (e.g.
not enough disk space?).
