- use a swapfile (can be on LVM) with a low priority
- use a swap partition on LVM with a low priority

How about fixing the memory leak?  :-)

Anyway, in most cases HD space is cheap and you can easily
allocate 3-4 times your RAM -- if you need more, you have a
bad leak or should definitively buy more RAM.

In all other cases, you can add swap space on the fly.  And if
you have multiple fast hard disks, do make a swap space on them
all (or even better on each raid system) and use the kernel's
inbuild ability to strip over them (set the priority identical).
