      Description

      When running C or C++ console application on Windows error occurs: "Cannot obtain a handle to the inferior: The parameter is incorrect".

      Problem seems to occur because user application may finish execution before ConsoleProcess::readStubOutput() function is able to process information (PID and thread id) provided via pipe by qtcreator_process_stub.exe and call OpenProcess() on time. Thus OpenProcess() is being called on non-existing process with closed handle, which leads to error.

      I was not able to dig into code enough, but I think qtcreator_process_stub.exe should wait for ConsoleProcess and keep handles open (do not call CloseHandle(pi.hProcess) and CloseHandle(pi.hThread) until it is signaled by ConsoleProcess.
