Handling Ctrl+C/Sigint in multithreaded run

Hello everyone,

I want to handle Ctrl+C event (crossplatform on Windows/Linux) to close my application, storing all status of detectors and histograms.
When G4 was singlethreaded it was simple, I had

G4RunManager *runManagerTop;

before main, code like

#if defined (WIN32)
BOOL CtrlHandler( DWORD fdwCtrlType )
{
G4String a;
G4double pt;
G4int pn;
switch( fdwCtrlType )
{
case CTRL_C_EVENT:
printf( “Ctrl-C event got\n\n” );
((RunAction*)runManagerTop->GetUserRunAction())->eofRunAction(1);
runManagerTop->AbortRun();
return FALSE;

case CTRL_BREAK_EVENT: 
  printf( "Ctrl-Break event\n\n" );
  return( TRUE );

default: 
  return FALSE;

}
}
#else
void CtrlBreakBackend(int sig) {
((RunAction*)runManagerTop->GetUserRunAction())->eofRunAction(1);
runManagerTop->AbortRun();
}
#endif
void handleCtrlCEventInit(G4RunManager *runManagerMain) {
runManagerTop = runManagerMain;
#if defined (WIN32)
SetConsoleCtrlHandler( (PHANDLER_ROUTINE) CtrlHandler, TRUE );
#else
#ifdef SIGBREAK
signal(SIGBREAK, CtrlBreakBackend);
#endif
#endif

and called from main after instantiating

G4RunManager * runManager = new G4RunManager;
handleCtrlCEventInit(runManager);

(eofRunAction(1) is my user function at RunAction that handles the saving).

But with multitreaded G4 it fails to work,
First, runManagerTop->AbortRun() seems to do nothing,
Secondly, I cannot access merge function of Run to put all data together.

Are there a proper way to handle Ctrl+C/Sigint signal in multithreaded application?
