  Log:
  Fix select and poll use in LWPs.
  
  When select(2) or poll(2) puts to sleep a LWP, the LWP may never be woken up
  when the events waited for occur because the TID of the LWP is not saved in
  the selinfo structure by selrecord().
  
  si_tid is not initialised explicitly anywhere but happens to bet set to 0, so
  the problem was not apparent for the initial LWP created at process
  construction time.
