It uses the "statvfs()" function, which should return how much space is 
available for unprivileged users (i.e. non-root users). Same info as a 
"df" will give you. If less than 5% is free, it will stop saving history 
logs.

The threshold can be changed via the --minimum-free=N option to 
xymond_history.

It is safe to remove files in the histlogs and hostdata directories. 
Using "trimhistory" is the recommended way of doing it.
