Describing it in more detail.
Alright, I can now reproduce; even with v0.2.4.16-rc (git-
dcf6b6d7dda9ffbd). I missed that you '''only''' deleted `cached-*` files.
Here's the log I get with your config. One can see the 60-second-wait.

Aug 22 11:40:46.442 [notice] Parsing GEOIP IPv6 file
/usr/share/tor/geoip6.
Aug 22 11:40:46.486 [notice] We were built to run on a 64-bit CPU, with
OpenSSL 1.0.1 or later, but with a version of OpenSSL that apparently
lacks accelerated support for the NIST P-224 and P-256 groups. Building
openssl with such support (using the enable-ec_nistp_64_gcc_128 option
when configuring it) would make ECDH much faster.

Aug 22 11:41:50.891 [notice] I learned some more directory information,
but not enough to build a circuit: We need more microdescriptors: we have
0/4314, and can only build 0% of likely paths. (We have 0% of guards bw,
0% of midpoint bw, and 0% of exit bw.)
