Description
The use of active_devices might not be thread safe if this library is used in more than one thread. Putting a new key in active_devices could cause it to be reallocated in one thread while another thread is reading which might cause undefined behaviour.

Research direction
Start by locating every read and write of active_devices in the repository and checking how threaded use is exercised. Reproduce the reported concurrent access if possible, then add coverage for the concurrent behavior; done means reading active_devices while another thread adds a key no longer causes undefined behavior.
