Why would we ever block? Based on the original issue, I thought this was basically an event filter, and that you planned to make it an event filter+map in the...

I've been messing with the PR to make grabbing work in Linux/X server and I'm having difficulty. One option I'm considering is using uinput, not X. Grabbing with uinput would...

Libevdev is lower than X, as it operates on "device files" in `/dev/input/`, just above the kernel level. It is possible to mess with device files more directly with ioctl...

After some investigation, most `TimeSpan` constructors can be made constexpr, but most `DateTime` constructors can't without C++14 constexpr features (Arduino currently uses C++11 by default).

If Arduino ever makes C++14 the default, [This stack overflow question](https://stackoverflow.com/questions/7960318/math-to-convert-seconds-since-1970-into-date-and-vice-versa) has some code that might be worth borrowing from.
