Memory currently widely used is PC3200 which means that 3.2GB/s can be _read_. The write performance is at about 1.1GB/s according to aida32. This means that timeslicing at 200Hz and above limits the size of memory chunks that can be written to within one timeslice to 5.5MB or less. So that is the space bound to variables we are talking of.

Better use "if" instead of "when", because in general the compiler
cannot see whether a variable is assigned to before use.

As pointed out above at least arrays occupying more than 5MB are of interest.

No, not yet.
