chdir is only thread safe to the extent that corruption won't occur.
If one thread is using relative paths, and another is doing a chdir-based traversal (as using the nftw function, for instance), that first thread's accesses are messed up.
This is why POSIX now has various -at functions; the provide stable relative access.
