453	Modules are initialized twice in single-process mode for Win32	Kroward 1		"There is feature of nginx to run Nginx as single process with 'master_process off'. Documentation says that this is for debug only, but it is very useful in Windows. In windows only one worker is possible, so using this option is acceptable I think.

Actually setting 'master_process off' solve the problem with shared memory on Windows 7+, and enables to use modules like 'limit_conn' which rely on shared pool. ''(Why this problem with shared memory exist at all if we run single process?)''

The only problem that 'win32/ngx_process_cycle.c' initializes modules twice in this mode, one time in procedure ngx_single_process_cycle() and second time in ngx_worker_thread().

Because of this open file descriptors become doubled and select() fires messages to log:
[alert] 2780_2832: select ready != events: 1:2

Removing module initialization loop in ngx_single_process_cycle() fixes this issue.
