This happens in finalize(), which is called just before the process
exits. There are no subsequent allocations, which means this should be
controlled by the FEATURE_CLEAN_UP option, and not freed in normal builds:
config FEATURE_CLEAN_UP
bool "Clean up all memory before exiting (usually not needed)"
default n

As a size optimization, busybox normally exits without explicitly
freeing dynamically allocated memory or closing files. This saves
space since the OS will clean up for us, but it can confuse
debuggers
like valgrind, which report tons of memory and resource leaks.
Don't enable this unless you have a really good reason to clean
things up manually.
