Fun project- I didn't even realize this was possible with non-realtime Linux. Apparently you can turn off all interrupts for awhile on the Pi without bad effect other than the system being unresponsive. Probably date/time clock gets slow (?)

Indeed selsinork, I've got one of those OpenBench Logic Sniffer boards myself, and I agree it's a very useful tool for very little money. I picked up one of the acrylic cases for it from SK Pang as well, looks very tidy and safe on the workbench --- http://www.skpang.co.uk/catalog/acrylic-case-for-openbench-logic-sniffer-p-901.html
Ditto my Bus Pirate, another open hardware board from Dangerous Prototypes which I've recommended here before and is another useful gadget. Mine is in one of those SK Pang acrylic cases too, incredibly tiny and cute.
It gives me a chuckle when these "amateur" instruments look so much prettier than their costly professional counterparts. 
I have to say though that I'm not too happy with the software for the OBLS, the "Alternative OLS Client" version of the old Sump software. I don't find it very friendly and usable as it could be, although Jawi is still busy working on it so I'm sure it'll improve. I keep getting the itch to hack on it myself, maybe I will one day. At least it's much more usable than the Sigrok client, which is still at a very early stage of development.
Morgaine.
