Hi,

i don't think that it's the right way to increase memory for such 
memory-expensive script.
In fact the script should be optimized not to use so much memory.
With mysqldumper, a former project of mine, we had the same problems - 
saving GB-databases with memory- and timeout-limits of a normal 
webspace, and we solved it by partly doing this and calling the script 
again to continue at last position.
Some kind of this technique could solve such problems impexp has, same 
in EM.
