The XAllowEvents(3) function releases some queued
events if the client has caused a device to freeze. It has no
effect if the specified time is earlier than the last-grab time of
the most recent active grab for the client or if the specified time
is later than the current X server time.
Some numeric value falls outside the range of values accepted
by the request. Unless a specific range is specified for an
argument, the full range defined by the argument's type is
accepted. Any argument defined as a set of alternatives can
generate this error.
