Oh.... (reconfig, recompile, reboot, retest).
Yes, you are right.  Drop ACPI_DEBUG and there is no noticeable pause
while reading /state or /info.

Thanks for that.

Still, it would be nice to have a proper fix.

If anyone wants to track this down and can suggest how I find out how
DEBUG is slowing things down so much, I'm happy to be a guinea pig.
