Crash on Export

I was having another look at "Combine(merge mesh)". It appears to be using an excessive amount of memory.

With the example of 1000 box(6000 polygons). I "Combine(merge mesh)", which took over a minute to complete, and checking memory usage, Nvil was using approx 6.6 GB of memory. (forgot to add:- After performing the "Combine(merge mesh)", I closed Nvil. The UI closed, but Nvil remained in memory for another few seconds, in those few seconds, Nvil started using 2 CPU cores, and memory usage increased to approx 12 GB)

Thinking it may be a problem specific with 64 bit version. I checked in Dec-23-13 build(32 bit), and attempted "Combine(merge mesh)" on 600 simple box. It caused error of "Out_of_memory"(approx 1.4 GB).

How is it now?

Very much better. I think that is now OK.

Many thanks.
