I think I've found a workaround. I found a list of environment variables
[1] you can set to affect the GC behaviour, and the first one I tried
(GC_RETRY_SIGNALS=0) seems to have had the desired affect, in that the
crashes/restarts have stopped.

I've sent a patch [2] to apply this setting as part of the service.
