* * pinfo.cc (pinfo::init): Move everything but the MapViewOfFileEx out of theChristopher Faylor2005-01-221-57/+68

(sig_send): Ditto. Also remove ill-advised test for !myself->sendsig since this is an indication of a process which is still initializating -- it is not an error. (child_info::sync): Don't set exitcode here. Assume that will happen in proc_waiter, if necessary. * spawn.cc (spawn_guts): Delay "wait_for_myself" logic until later. Don't wait at all if the process has already exited. Reflect movement to pinfo::exit.
