This kind of change sets off alarm bells. The big question is why are
you seeing exceptions? I suspect you're forking off processes within hob
which are then confusing the waitpid code. I'd have to ask why the UI is
forking processes when a build is running and why we're suddenly started
seeing this...

So can you please explain the problem further so we can fix the real
problem? I did look at #2186 but that doesn't help me either :(

Cheers,

Richard
