multithreading and chdir

Hello,

Im going through a code, where, it seems the issue is due to the way threading implemented.

I just know basics of threading

I am trying to understand the affects of multithreading on chdir, and how can it be made threadsafe.

May be these hints help me understand the concept and apply in my issue (code is huge, so I am trying to understand the code base first)

Thanks
