Description

split from #95 a way to combine uiMainStep() with select() or poll()

on GTK+ and OS X this should be fine

on Windows I don't know one thing:

What would the equivalent of a select() be on Windows? It appears MsgWaitForMultipleObjectsEx() does not accept file or socket handles. Does it have to do with OVERLAPPED? I see GLib accepts file handles on Windows...

Research direction
Examine the current uiMainStep implementation in the codebase (likely in main.c or similar). Understand how it works on each platform (GTK, OS X, Windows). For Windows, research the equivalent of select() for file descriptors and how GLib handles it with GPollFD. Consider implementing uiMainStepPoll() using MsgWaitForMultipleObjectsEx or alternative Windows APIs. Reference issue #95 for context.
