I doubt this.  Standard recommended procedure is to disable keyup events
in all applications that don't need them (I think they are even off by
default).  Enabling key-up events halves the amount of type-ahead
possible, since the system event queue can only contain 20 events
(unless this limit has been upped since the 64K ROMs).

Besides, the Finder should be smart enough to reset its event mask.

My guess is that the low-memory global containing the double-click time
was reset to zero or something negligible small.
