Xpra: Ticket #1742: better diagnostics

When things go wrong we rely on "xpra info" to capture the state of the system so that we can figure out what is going wrong, we may need to add more information in there:

@maxmylyn: this may help diagnose performance issues.

This is all very useful, but I'd like to request another metric to add - iowait - it should be fairly trivial to calculate, and would offer a good metric for users with older/slower Hard Drives. One of my test boxes has a very very slow disk, and as such when I'm doing IO intensive actions, the iowait will go up (as viewed via https://netdata.io - very useful visuals), while the CPU utilization stays notably low. This would be useful in pointing out slow storage (or other devices).

I don't think it is at all, please file a separate ticket for that.

Very well, closing this one.
