I did look at using libev, but I was saddened to find that it uses
floating-point time values, which isn't really going to fly on the platform
I'm doing this for (Maemo/MeeGo on ARM).

It also seems rather perverse to go from int milliseconds (libdbus) to
floating-point (libev) back to int milliseconds (poll/epoll/select)...

The fact that its error handling is basically abort() also puts me off.

It looks as though the main loop refactoring I'm doing at the moment would
be necessary for either epoll or libev, FWIW.

Embedded code copies, just say no...

(Debian has a shared library package for "libev with the default ABI",
though.)
