The updateConfig command doesn't actually build anything. All it does
is triggers a parse of the base configuration, it isn't even parsing
recipes, just the bitbake.conf and layer.conf files.

Think of updateConfig as just bringing the two ends of the connection,
client and server into sync.

I'm a bit worried that if the system is so overloaded it can't do that
in 60s, we have bigger problems.

What is BB_NUMBER_THREADS set to and how many CPU cores? Spinning media
or SSDs? What are the system load numbers when this happens?

I think that if this startup timeout is happening, there will be other
issues and you need to resolve the overloaded system problem rather
than just move the timeout problem to somewhere else.
