From mprime2415 to mprime255

Used to run 8 copies of mprime2415 like so:
./mprime -a1
./mprime -a2
.
.
./mprime -a8

Now that the magnificent mprime2415 is there, I tried:
./mprime -a1 -a2 -a3 -a4 -a5 -a6 -a7 -a8
but it seems to only pick up one of the work sets.

At the moment 7 of the 8 threads are "waiting for the server".

Worker #1 thread is kicking butt though with all the other contenders sleeping.. 0.066 sec per iteration time.

Any suggestions to convince the 7 lazy worker threads to get going with the -a2 -a3 -a4 ... -a8 files would be appreciated.

Maybe they'll get new work from the server, but it's down at the moment

Mkay... as soon as the server came back, the seven idle threads got new exponents and are now busily factoring. I guess the migration over was not <cough> smooth.

Unless you're keen to help debug the new server, I really don't see the advantage of going to v25.5.

The automatic management of 8 cores/threads is a real benefit.
In mprime2415 I had to manage eight separate instances of mprime, each with its own fileset.
