`dmdtags` does not run in the background, so any memory it uses 
will be freed at process exit, as soon as it has finished writing 
the tags file. And because it does not do any semantic analysis, 
only parsing, it does not use much memory while running in the 
first place.

According to `/usr/bin/time`, on my personal machine, using 
`dmdtags` to generate a tags file for all of Phobos takes 
slightly less than 1 second and has a peak resident set size of 
around 100MB.
