Multithreading considerations ?

[Sunslash]

Hello,

First, I would like to thank you for this very nice library, it has helped us in many ways already.

We have a project where we have a single cpp_redis::client instance shared by multiple threads. It seems to be working, but I would like to ensure that we are not doing anything wrong.
Could you tell me which functions should be protected by a mutex in our application ? I guess that connect() is a prime candidate, but I'm not sure about sync_commit and commit.

Regards
