llthreads

Lacks mechanisms for data passing between running threads, forcing reliance on external libraries like ZeroMQ or sockets, which the README explicitly admits and recommends.

If join() is not called on joinable threads, the garbage collector may cause random pauses or freezes, as warned in the example, leading to potential resource leaks and unpredictable behavior.

For meaningful communication, additional libraries must be integrated, increasing project complexity and setup overhead beyond the core threading functionality.

Relies on pthreads for Unix and WIN32 threads for Windows, which can introduce portability issues or require platform-specific adjustments during installation and usage.
