Uh, no. When you get new work, it will finish the old work first... IF
the new work doesn't need to be further factored. However, ANY factoring
takes priority over a LL test, even one in progress. If your "new work"
was previously factored to 58 bits, but Prime95 wants is factored to 63
bits before starting a LL test, it will STOP the LL test on the current
exponent, and finish factoring the new one. Once the factoring is done, it
will go on to complete the original LL test, followed immediately by the
new LL test. If a factor is found for the new number, another number will
be requested, and it, too, may need advance factoring prior to completion
of the original LL test.

There's nothing "magic" about the 7% level. It won't work on a
Lucas-Lehmer test on a new exponent until the LL test on all older
exponents are done. It only bumps FACTORING up to the front of the queue,
so regardless of the size of the exponent, you will only have to wait a
matter of days to find out whether your original number is prime or not --
not months to get to "7%"....
