Well it seems the acpi_button driver doesn't notify anyone on close(). It
should probably also refuse select() requests when the fd is already
closed, or is it already enforced by the driver API? A bit of locking
would be needed too.
Same for acpi_lid.

at something bad occuring even before shutdown. For instance if I start
using this install normally (instead of doing the above 30 seconds "KDL
recipe"), I get strange userland crashes in Terminal, WebPositive ...
Sometimes ending up with a KDL (EDIT: at time of reboot reboot, never
before IIRC), sometimes I can reboot after the W+ crash or Terminal crash
without getting a KDL. Didn't collect real data on that aspect yet though.
Here I'm unsure it's really related.

Thanks for the info.
