* child_info.h: Reset magic number.

Browse Source 
(child_info_spawn::wait_for_myself): Move function to sigproc.cc.
* pinfo.cc (is_toplevel_proc): Delete unneeded variable.
* sigproc.cc (child_info_spawn::wait_for_myself): Move function from header to
here.  Do all setup required to properly wait for top-level execed process to
exit.
* spawn.cc (child_info_spawn::worker): Attempt to properly handle _P_DETACH.
Set wr_proc_pipe if top-level process even when execing.  Just call
wait_for_myself() to...  wait for myself.  Don't call cleanup twice.
