After I posted last night, I realized that yes, I did need to cut the door jambs. So I got up this morning, went to my hair appointment (I'm a lovely shade of blonde again), had lunch, dawdled home, checked my email and Facebook and craigslist like 15 times each, then woefully set to work.
I don't have a jamb saw. They're really one-trick ponies - they only cut jambs. They cut the hell out of jambs, but it's an expensive purchase for one home, even if it is The Home of Infinite Doors. My best friend back in Memphis has a jamb saw - I could find it in his toolbox blindfolded. Alas, he is 2000 miles away, so I made do.
I tried my trusty hacksaw, but it didn't work as well as I'd hoped, so I turned to the coping saw. It worked well enough, so I spent three freakin' hours cutting 18 door jambs. I got pretty disgusted a couple times and almost went to town for a Dremel, but I contained myself and got it done.
Now. Back to cutting oak.
