    The only way
    I can think of would be to flush the internal queue and then 
    do a select on the file number that Xlib is using to talk to the server.

Right.

    However this is not very portable.

Also Right.

    What I would like would be a version 
    of XNextEvent with a timeout parameter that can take sub-second values.

But many others will argue that this isn't sufficient, since they need to
wait on other things besides X events, or they need to wait on multiple
displays, or ...  It isn't obvious to me what a reasonable and portable
interface would be.
