The P4 optimization is obviously the "biggy". However was there not
once something about changes being neccessary (to the server as well
as to the client) to incorporate P-1 factoring as a seperate
assignment type?
I think we're reaching the point where we may need a new release of
v20. The point is that we now have fairly extensive overlapping of
double-checking with first runs which may have been done with v20, in
which case the double-check job is wasting its time running P-1.
People running LL tests may also be needlessly repeating the P-1
factoring stage; a fair percentage of assignments are abandoned &
recycled with P-1 having been finished and reported to the server.
A quick "kludge" would be to have the client check a local copy of
the pminus1 database file, even though the user would have to
download the file & unzip it manually. (Proceed as at present if the
pminus1 file is missing.)

Yeah, don't fix what ain't broke. Defect to linux & forget about
fashion fads affecting program names ;-) But, if you must change the
name, go for PriMe.

Still, the CPU time required to write one line to the display is
considerably less than that required to execute one iteration of an
LL test on a large exponent.
