I've a strange issue. pserve --reload has stopped reloading the templates. It is reloading if some .py-file is changing, but won't notice .mak-file changes anymore. 
I tried to fix it by:

Checking the filepermissions
Creating the new virtualenv, which didn't help.
Installing different version of mako without any effect.
Checking that the python is used from virtualenv
playing with the development.ini. It has the flag: pyramid.reload_templates = true

Any idea how to start debugging the system?
Versions:

Python 2.7
pyramid 1.5
pyramid_mako 1.02
mako 0.9.1

Oh my,
I found the thing... I had <%block cached="True"  cache_key="${self.filename}+body"> and the file inclusion was inside of that block.
Cheerious:)
