  #include <dlfcn.h>
  #include <omp.h>
  
  int main() {
  #pragma omp parallel num_threads(2)
    {
      if (omp_get_thread_num() == 0) {
        void *h = dlopen("./liba.so", RTLD_LAZY);
        void (*ptr)() = dlsym(h, "foo");
        ptr();
      } else if (omp_get_thread_num() == 1) {
        void *h = dlopen("./libb.so", RTLD_LAZY);
        void (*ptr)() = dlsym(h, "foo");
        ptr();
      }
    }
  }

Did this as a basic test, let me know if it's broken. It was fine initializing but it hung somewhere else when we try to launch the kernels. Same behavior before this patch so it's probably just broken elsewhere.
