 murb reports the following error message in 0.2.3.10-alpha:
 {{{
 Dec 28 15:59:37.000 [err] _circuit_mark_for_close(): Bug:
 circuitlist.c:1222: _circuit_mark_for_close: Assertion ocirc->rend_data
 failed; aborting
 }}}

 There were no relevant notices or warnings before this message.

 I see several code paths which can set a circuit's purpose to
 `CIRCUIT_PURPOSE_C_INTRODUCING`, then mark it for close before its
 `rend_data` field is set; there's no way we can get rid of those paths.
 Time to remove this assertion.
