Comment(by arma):

 For future reference, here are two more I haven't resolved yet:
 {{{
 ==1852== 1 bytes in 1 blocks are still reachable in loss record 1 of 30
 ==1852==    at 0x4C244E8: malloc (vg_replace_malloc.c:236)
 ==1852==    by 0x2125E7: _tor_malloc (util.c:144)

 ==1852==    by 0x11A24E: do_main_loop (main.c:1861)

 ==1852==    by 0x5EFCC8C: (below main) (libc-start.c:228)
 }}}

 (Is there a proper way to free the result of an evdns_base_new()?)

 {{{

 }}}

 (Looks like we'll want to add a compat_free_all() or the like, so we can
 reach into compat and free the mutex when we're done.)
