Re: [PATCH] vbscript: Replace custom buffer management code by BSTR based helper.

[Jacek Caban]

Hi Dmitry,

The problem with using BSTRs is that you need to realloc every time 
something is appended. In cases like [1], the current approach uses one 
heap_alloc and one SysAllocString. You patch would need one 
SysAllocString and 6 reallocation.

That said, I wouldn't mind your approach in general, but I don't think 
it's an improvement over the existing code.

Thanks,

Jacek
