Bring back delay before management is ready

Commit 2b1e586

"Replace Sleep by a Wait function that pumps messages"

replaced Sleep() with a wait function which also processes messages.
However WM_MANAGEMENT message in some cases requires actual delay to be
processed. To achieve that, bring back original Sleep().
