I have upgraded to 1.8 and noticed import puppetclasses takes unusually long. After investigating, i figured out foreman now reads the classes from proxy twice:

217.28.94.7 - - [04/May/2015 13:57:27] "GET /puppet/environments HTTP/1.1" 200 47 0.1897
217.28.94.7 - - [04/May/2015 13:58:12] "GET /puppet/environments/production/classes HTTP/1.1" 200 552093 40.5052

217.28.94.7 - - [04/May/2015 14:02:08] "GET /puppet/environments/common/classes HTTP/1.1" 200 2 0.3390

Apart from this twicefork, would it be possible to trigger update just of one puppet module ? It could be easily scheduled via API on postcommit hook and accelerate new class import to seconds, instead of minutes.
