Eliot,
Is there a way to save the image given that it is non-responsive? Otherwise (and this could be "how it is") one would have to apply the fix before having the problem. Just curious. Should we all periodically take a semaphore head count in our images?
I try to leave a reasonable trail of backups of working images just in case I do something stupid; a little uncertainty can motivate cautious behavior...
Hmm... I think what's needed is a command-line parameter. Give me a few...

Hi Janko,
you need to /save/ the image having applied Smalltalk vm maxExternalSemaphoresSilently: 3000. This must be set in the image at start-up, not after the image has loaded. i.e. the VM inspects the value saved in the image header and applies the value *before* the image starts running.

The log you posted contains the string "Not enough space for external objects, set a larger size at startup!" Maybe a command-line switch to the vm will give you more memory and a way to get the image going?
Smalltalk vm maxExternalSemaphoresSilently: aSize would be the line to include. If the script passed on a command line is higher in the startuplist than the InputEventSensor, it would get it working again.
Ok, I'm back having time to look at this problem and I made a start.st< http://start.st> script below, start the image with it, but get the same blank screen as you can see in attached screenshot. Ctrl or Alt . doesn't help.
start.st<http://start.st> Smalltalk vm maxExternalSemaphoresSilently: 3000
./Contents/Linux/squeak ./Contents/Resources/waste.image start.st< http://start.st>
Any more idea? Otherwise I'll start to recover from changes, but starting this nonresponsive image would of course be faster solution:)
