viewRefreshTime is always 4 seconds in Maps

Which products are affected?

Google Maps  (The KML value for viewRefreshTime is respected by GE)

What steps will reproduce the problem?

1. Browse to... http://maps.google.com/maps?q=http:%2F%2Fwww.geodesy.net%
2FPrescottMdbTest%2FParcels.kml&ie=UTF8&ll=34.540032,-
112.467277&spn=0.002152,0.003685&t=m&z=18

2. Pan the map a little and notice a 4-second delay before update.

What is the expected output or behavior? What do you see instead?

KML updates should occur starting 1 second after a pan or zoom in Maps, 
based on the KML setting for viewRefreshTime.  Instead, Maps waits 4 
seconds before starting the KML update.

What application versions (if any) are you using?

KML 2.2

Which operating systems and browsers are affected?

Windows XP SP3, IE7, Firefox2 (others possibly)
