This would depend on your -N setting.
A little experimentation shows that the present multiplier for -B is
about 8350 bytes and the multiplier for -N about 14580 bytes on my
system (HPUX), which extrapolates to a fixed base of about 250K plus
the -B and -N contributions. In reality I believe the computation
is somewhat nonlinear, but that's probably close enough for starters.
