P-1 factoring wasting cpu cycle?

[engracio]

A couple days ago I downloaded a wu and my ws did what it was suppose to do. Ran P-1 factoring and found no factor and continued to prp the wu.

UID: engracio, 55459*2^19355890+1 completed P-1, B1=55000, B2=426250, We1: F4C8BB45, AID: 00000000000000000000000000100F9D

Last night I guess we had a power outage and it resulted an error on Prime95. I decided to cancel the prp and grabbed another wu due to the error.

While checking my other ws in the herd I found the same wu now being P-1 by another ws. Knowing full well it has been P-1/factored already by another machine. Is this acceptable duplicate of work??? It takes about an hour now to P-1 a wu on a Q6600 with 1 worker and 2 threads.

More importantly what happens if a factor was found by the ws, would it continue to prp the wu?? Just asking.
