in question vary per OS: on Windows the problem is that WM_TIMER sometimes goes off too early, so that GetTickCount() is right and the callback time is wrong, whereas on Unix the problem is that my GETTICKCOUNT implementation comes from the system clock which means it can change suddenly and non-monotonically if the sysadmin is messing about (meaning that the timing of callbacks from GTK or select timeouts is _more_ likely to be right than GETTICKCOUNT). This checkin provides band-aid workarounds for both problems, which aren't pretty but ought to at least prevent catastrophic assertion failure. [originally from svn r5556]
