Querying battery (or temperature) using ACPI takes quite some
resources, which makes the battery discharge faster. It doesn't make
much sense to have it queried as often either. So, when using ACPI:
1) set battery query period to 10s minimum
2) set temperature query period to 5s minimum
using legacy import is dangerious as it is unencrypted by default,
so a man in the middle can force the fallback to import protocol
and then take over the connection to the remote machine gaining
full access to is.
the numbers from /dev/sysstat overflow on 32bit, so have
to do subtraction modulo 2^32 as we calculate with 64bit
integers.
thanks mischief for reporting this.
fix the default note handler for event programs. only handle non system
notes or notes in the slave processes. for interrupt in the main process,
just call exits() which will do the cleanup and restore window label
properly.
this makes completely overriding the note handler in gping and
stats uneccesary.
