Note that if you do a default build, you'll get a debug build which, at
runtime, will load symbol info. Hartmut computed that this takes up 7Mb of
memory. If you want to use as little memory as possible, you can do a
release build (copy config.template.xml to config.xml and change the DBG
value to 0), or you can prevent symbol info from being loaded by adding
/NOLOADSYMBOLS to the load options in freeldr.ini.
