   I noticed that the ostest with esp32-devkitc:smp (real board not qemu) causes a deadlock.
   
   ```
   user_main: waitpid test
   
   Test waitpid()
   waitpid_main: PID 28 Started
   waitpid_start_child: Started waitpid_main at PID=28
   waitpid_main: PID 29 Started
   waitpid_start_child: Started waitpid_main at PID=29
   waitpid_main: PID 30 Started
   waitpid_start_child: Started waitpid_main at PID=30
   waitpid_test: Waiting for PID=28 with waitpid()
   waitpid_main: PID 28 exitting with result=14
   waitpid_main: PID 29 exitting with result=14
   waitpid_test: PID 28 waitpid succeeded with stat_loc=0e00
   waitpid_last: Waiting for PID=30 with waitpid()
   waitpid_main: PID 30 exitting with result=14
   waitpid_last: PASS: PID 30 waitpid succeeded with stat_loc=0e00
