Matthew, this happens *all the time* to me and to other developers I
work with when building software. All the time. I fine-tune my
ninjaargs to figure out the highest -j I can use when building
without killing my desktop. We shouldn't have to do this. We're not
talking about out of control processes, we're talking about running
make or ninja exactly as designed: it's expected to spawn a huge
number of GCC subprocesses (4, 8, 32...), each one will want 1-2 GB
of RAM... the Fedora desktop should remain smooth and performant
under this load and throttle ninja as needed, not freeze up.
Sorry if I wasn't clear: I didn't mean that this wasn't a problem. I meant
that given how badly this already sucks, the possibility of it happening
right when hibernating is ... how to say... what's the opposite of icing on
the cake? Sure, your system may not hibernate properly, but at that point it
was already doomed anyway.
