Delaying it a little is probably ok, but weigh that against the
frequency/severity
of the problem that Pavel's fix addresses:  ie sequential writes to some
versions of Windows 7 and Windows Vista can fail partway
through large file copy (which also causes those servers
to become unresponsive to subsequent connection requests
as well) so the fix does address a hot problem.
