See the rw-FAQ, question
2.4 There seems to be a limit on the memory it uses!
Also, you will get a message when it runs out saying
Reached total allocation of 255Mb: see help(memory.size)
and you could always as a last resort do as it says ....
I should say that on Windows 9x systems you really don't want to use your
virtual memory, and for NT/2000 you will see a large performance hit.
