check your "ulimit -v". Xine seems to hog at least 256MB of virtual address space, even if it's not actually backing that with physical memory.
Ordinarily, I use the ulimit mechanism to automatically kill runaway processes that are sucking too much vmem (on the assumption that it is all backed with pmem). Without ulimit, Linux would be swapping so badly that I wouldn't be able to run "top" to kill the offending process.
But now, I have to up this figure just for xine...
