Darn. That's the major hassle with using doc-view and I thought having
async functionality would make it less painful.

Just did a git pull and it said I had the most up-to-date version
already. I didn't see anything in the source - maybe you haven't
checked it into your git repository yet?

The convert process seems very resource hungry as my Powerbook G4
slows to a crawl (and is basically unusable) when I'm converting a
large (2MB) PDF file. On small PDF's, it's still usable (but slow). I
thought that a batch option would provide an alternative that might
not be as intrusive.

How about "b" (for browse) or "V" (for View)?

At the moment, I would be happy to just replace my Powerbook with a
dual core computer with 4GB of RAM!
