What steps will reproduce the problem?
1.x86/nonvga_debug at r14561 with lua & exec:
svn up -r14561
svn up third-party/lib/luasocket/Makefile src/cmds/net/httpd.c 
src/kernel/task/resource/res_argv.c 
src/include/kernel/task/resource/task_argv.h src/compat/posix/proc/exec.c
make confload-x86/nonvga_debug
make cacheclean
make clean
2.conf/mods.config
+ include embox.arch.x86.vfork
+ include embox.compat.posix.proc.vfork_stop_parent
+ include embox.compat.posix.proc.exec_stop_parent
+ include third_party.cmd.lua(luasocket_support=true)
+ include third_party.lib.luasocket
