memory leak occurs when creating a new type

[zaxrok]

A memory leak occurs when this part with_service_schemas(service_class) is used.
This is a serious problem, so we need to take quick action.
And I found the code that caused a memory leak so I look forward to your efforts.

pyros-schemas/pyros_schemas/ros/schemagic.py

Line 101 in 9e3debe

MsgSchema = type(ros_msg_class.__name__ + 'Schema', (RosSchema,), members)

Please check

Oh I didnt check for leaks yet... Good to know, thanks. Which interpreter you use ? How did you launch that code ? What is the minimum code to reproduce the problem ( http://sscce.org ) ?

We also need to think about automatic testing, to make sure we don't have the same issue in the future.

How would you design tests for memory leaks ? We need to cover as much code as possible and test that no leaks happen.

Ideally we should merge the leak tests in before the PR #9, to quickly prove there are leaks before (in master), but there are gone in PR branch.
