Is it possible for "ccall" to call the shared library created by PackageCompiler.jl?

Sure, but these are aspirational goals. Here is the current code.

JuliaLang/julia/blob/master/src/init.c#L212


      
          if (jl_all_tls_states == NULL)
              return;
          
          
jl_task_t *ct = jl_current_task;
          
          
if (exitcode == 0)
              jl_write_compiler_output();
          jl_print_gc_stats(JL_STDERR);
          if (jl_options.code_coverage)
              jl_write_coverage_data(jl_options.output_code_coverage);
          if (jl_options.malloc_log)
              jl_write_malloc_log();
          if (jl_base_module) {
              jl_value_t *f = jl_get_global(jl_base_module, jl_symbol("_atexit"));
              if (f != NULL) {
                  JL_TRY {
                      size_t last_age = ct->world_age;
                      ct->world_age = jl_get_world_counter();
                      jl_apply(&f, 1);
                      ct->world_age = last_age;
                  }

Julia does not dynamically launch threads at the moment. They are allocated on startup. They are only shutdown at process exit at the moment.
