     The effect of the blamed commit 7ef35b33936682c01f1c825b7d1b07567a691c12
     is that before the commit a process was failing to create due to NT image path passed to
     RtlCreateUserProcess(). That was wrong, NT path are what actually works on Windows and
     DOS paths do not. When the process creation working after the commit the new process started
     failing early in initialization due to the parent process unmapping the image section and
     remapping that as an anoymous mapping before the user part of process was initialized
     (build_main_module() needs correct image info from NtQueryInformationProcess( ProcessImageInformation ).
     The process failure at that stage makes parent process wait for 20 sec until timeout.
