+Summary: System.Diagnostics.Process.GetCurrentProcess() fails from spawned process
+I began to implement an automatic upgrade for my program and ran into this
+problem.  Here's the scenario:
+The program detects there's an upgrade available.  It downloads the new
+files for an upgrade, one of which is a shell script.  The program then
+uses Process.Start() to start the shell script and if successful, exits.
+Meanwhile, the shell script starts up and upgrades some RPMs.  When the
+upgrade is complete, the shell script attempts to launch the updated
+program.  The program needs to use Process.GetCurrentProcess() and gets an
+exception making that call.  The complete stack trace is:
+** (GetCurrentProcessBug.exe:30185): WARNING **: process_set_current: error
+looking up process handle 0x403
+Unhandled Exception: System.SystemException: Can't find current process
+in <0x00072> System.Diagnostics.Process:GetCurrentProcess ()
+in <0x00023> GetCurrentProcessBug:Main (System.String[] args)
+I will attach a sample program which shows the problem.
