Replace "Spin" with "Wait", or somehow note that we're waiting for the callback
at the end of Profile Creation.

Both here and above, line 202.

[Bernhard Bauer, 2015/03/02 21:06:45]

Done. (I used "run the message loop", as "spin" is sometimes used to mean
spinning the message loop, and sometimes means busy-waiting ("spinlock"), and
likewise "wait" sometimes means blocking the thread, and sometimes means running
a message loop.)
