[win-pv-devel] [PATCH 05/14] Add a short Sleep between CreateFile calls

[<owen.smith@xxxxxxxxxx>]

From: Owen Smith <owen.smith@xxxxxxxxxx>

If there is no delay, its possible for the second call to CreateFile
to fail with all pipe instances busy. Give the server end time to
get back to ConnectNamedPipe
