Presetting the "new" jib sheet as described, may be the way to go. Personally, I haven't had trouble on most boats treating the jib as an "orphan" to be tended to after the main has come over and been eased. But if you do, then do whatever you need to get comfortable.
What Boasun is describing is also known as the "chicken jibe" (meaning not jibing at all, typically when it's blowing stink and you want the rig to remain standing, and the boat to remain underneath it ;-). I describe it to students as akin to having a psychotic sniper next door, and your best friend, whom you want to visit, next door to sniper. You wisely go all the way around the block, even though a longer walk, in the interest of having it bullet (and death)-free. Consider this technique when it's blowing 20 or more.
And most important when jibing in a breeze, keep the bow headed no higher than a broad reach right after the boom comes over. If you don't arrest your swing in time, she'll keep on rounding up, and you'll end up broached broadside, with the tip of your boom in the water so you can't ease it. Not fun, though definitely an adventure.
