When reading or writing files rather use mmap() than memory buffers to save memory. DWG's can get quite big and we already have to keep a copy of the Dwg_Data structure in memory, plus it's input dat and output dat buffers.
problems: compat lib needed on windows, there are a few. But basically we just need two calls, which are trivial to implement. I already wrote that for some perl mmap library some decades ago.
