If I understand Gerhard correct, some functions take primelimit not as
an advice about the number of available primes, but as a directive to
loop over these primes.

Suppose I want to have a table of primes up to 1e9 (very easy with the
current PARI), say, to use forprime() with big primes.  This may
significantly slow down the functions which loop over *all* existing
primes.
