there is no limit, beyond the size of a pointer, and the limitations put on your
program by the operating system.

when the list is resized, you need to be able to hold an extra copy of the list
in
memory simultaneously, in worst case. the size of a list depends on the number
of items in it, not the size of the actual items, so the peak memory use for a
list
of size "size" is a little over 2*size*sizeof(pointer).
are you adding stuff to multiple large lists simultaneously? have you plotted
the
memory growth and compared it to the list size growth? if memory growth is
more quadratic than linear, you're probably fragmenting the memory. the only
solution to that problem is to use a better data structure.
