I found a weird, non-code partial solution: run some sort of constantly-updating graphical program in the background, like ico or something like that. I think the problem is that the X server or window manager goes to sleep and won't wake up until you get its attention. I also gave the X server real time priority in windows, but it didn't really help. With ico running in the background, alt-tab works fine. I didn't have it installed with cygwin, so I xhosted it back from my linux box. I hope this is a good enough clue for the X maintainers, I'd look for differences in the code around scheduling and see if there were any optimizations related to sleeping.
