Multithreaded Pitfalls

It is very easy to get your program to deadlock by resuming only a specific thread while other threads are still and hold a resource that the resumed thread might need.

libthread data structures are in user space and might get corrupted by bugs involving rogue pointers. In such cases one suggestion is to work at the LWP level with commands like lwps and lwp, which are analogous to their thread equivalents.
