[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Add to file system file named "doit.lua":
       os.execute("help")
       os.execute("ls")
2.  make confload-x86/lua-demo
3.  make
4.  ./auto_qemu
5.  embox>lua doit.lua
PANIC: unprotected error in call to Lua API (doit.lua:1: attempt to index 
global 'os' (a nil value))

ASSERTION FAILED at src/kernel/thread/sched_strategy/simple_queue.c : 194,
        in function runq_switch:

next != NULL
kernel debug panicQEMU: Terminated

What is the expected output? What do you see instead?
I prepare this file to execute commands "ls" and "help" consequently,
but error has occurred.

What version of the product are you using? On what operating system?
It was in r9054 , ubuntu, qemu.
