[ros-dev] Race Condition?

[Hartmut Birr]

Hi,

I would like if you can commit this changes or can send me a diff. The race
condition between the two locks is one of the major problems on smp
machines. An other problem is the registry. Some registry functions are not
thread safe, which results in wrong values and very often in a crash.
