What does that mean: ...can kill the app?
If this is to be understood as a rule of thumb, it is wrong (IMHO).
E.G. I was told here, that Crafty uses around 1MB of lookupdata.
It is certainly not killed by that.
In 1 MB you can have 4096 256-Byte lookup-tables, setting them up und
using them should keep the programmer busy for a while...
