rpc_H_PL2

[Greg Turner <gmturner007@ameritech.net>]

This fixes part of the deadlock problems with H_PL1.  Another other part 
of the problem was in the server parts and will be submitted only to 
wine-devel as H_PL3.  With both patches, RpcMgmtStopServerListen 
basically works, at least in the simple tests I've been performing.
