[Crash-utility] Threaded crash tool? Is it time?

Machines are getting ever bigger. I routinely look at crash dumps from systems with 2TB or more of memory. I'm finding I'm wasting too much time waiting on crash to complete a command. For example "kmem -s" took close to an hour on the dump I'm looking at now. Has anyone ever looked into mutli-threading crash? Given the kmem -s example above, a thread could be created for each cache (up to some defined limit of threads). Things like "foreach" could spawn threads. I'm sure there are lots of other opportunities. Yes, I know, it's open source, I should just go do it myself. Still, I'd like to hear pro's and con's on this idea. -- - jim
