If one really thinks this out, one may also come to the conclusion that this is not well spent time. Most of it can be achieved with current rsyslog just by configuring the system with gigantic swap space and let rsyslog use "insanely" large amounts of "main" memory for it's in-memory queue. The OS would then do exactly what a new queue system would do otherwise. The only potential problem would be system shutdown, where persisting unprocessed items to disk could take quite (too) long.
reading out of swap is known to be extremely inefficient, I think I remember reports of 10-20% of the expected disk speed because it gets horribly fragmented. preallocating a file and mmapping it would be far better.
