#23 Too long path of launcher puts RAA in an endless loop

[Hofi]

If launcher (and raa) are in a directory that has a long
path then m_hSignalEvent signaled state stays always
signaled and RAA gets into an infinite CreateNewProcess loop.
This situation might never happens but now no error got
neither from CreateNewProcess nor from launcher. Further
examining and an error dialog required to handle the problem.
