[Dev-luatex] os.execute: All command execution is disabled

Hi, all,
I'm trying to run any program with io.popen or io.execute and it's not working.

1) io.execute returns 'nil'
2) io.popen returns 'nil  All command execution is disabled' 

simple example:
\directlua{print (io.popen('ipconfig.exe'))}

winxp, texlive2009, luatex version: beta-0.40.6-2009110118

in file 'loslibext-1.c' i see that this output is returned if shellenabledp <=0.
so, question is how to enable shell execution! \pdfshellescape is removed from
that version.

Thanks, Linas
