r3886: Trying to understand delayed file write update times. Added another
test that uses 2 connections and queries the time via pathinfo, not fileinfo.
MSDN states : "When writing to a file, the last write time is not fully updated
until all handles used for writing have been closed." - but this is obviously
untrue. W2K3 seems to use a 2 second granularity for this. Next I'll try using
SetFileTime equivalent to see if this takes the same time to take effect.
