New Revision: 4797
URL: http://trac.nginx.org/nginx/changeset/4797/nginx

Log:
Merge of r4758: win32: fixed cpu hog after process startup failure.

If ngx_spawn_process() failed while starting a process, the handle of a
handle of a processes was closed but left non-NULL in the ngx_processes[]
array.  The handle later was used in WaitForMultipleObjects() (if there
were multiple worker processes configured and at least one worker process
was started successfully), resulting in infinite loop.
