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. Jeremy. (This used to be commit 2e47e241f98c3dba8be346cea726def38399eb97)
