Comment (by glynn):

 Replying to [ticket:863 rblazek]:
 > set_env/unset_env should release memory allocated for previously set
 value if a name is reused/deleted.

 That would require G!__getenv() to duplicate the value. Currently, it just
 returns the pointer. As the caller may hold onto the pointer indefinitely,
 the library cannot free it. Duplicating the value would require the caller
 to free it.

 I'm not sure this is worth it. Do any GRASS modules call G_setenv()
 repeatedly?
