Sorry, I missed your last mail as it went to my spam folder. Somewhy
your bug mails do not get threaded, did you use the 'reply' button for
subsequent mails? If not, please do.

The patch's idea looks good, but I think your patch introduces a memory
leak. How about the slight modification (attached). Could you please
confirm that it works for you as well?
