[Rg 136] [PATCH] update the Thin adapter for Thin 0.6.1

[Keita Yamaguchi]

Hi,

This patch updates the Thin adapter for Thin 0.6.1.

Thin version 0.6.1 stops Ramaze's spec tests because it removed
Thin::Server#listen! method and changed Thin::Server#start to start
port listening. This patch is a solution of the test failure, but
please be careful this is unconsidered for Thin version 0.5.4.

Regards,
Keita Yamaguchi
