I'm using D for small tools for about a year now and I never had 
to mess with GC. Most of the tools don't need to work on GBs of 
data and performance has always been good enough.

My "biggest" D tool is a custom scriptable code generator based 
on lua and sdl (sdlang.org) and even though it's implemented 
really badly, it performs good enough to be used in development 
(Currently we generate JSON serialization code for delphi with 
it).

I also wrote a simple parser for parsing delphi memory leak 
reports to show some statistics. Depending on how many leaks you 
have, these can get a bit larger, but I always got good enough 
performance with D.

Last tool I want to mention is a binary log file parser, which 
reads an proprietary log file and converts it into json. And even 
this is extremely fast.

So I don't think GC will be a big problem for smaller tools.
