Hello,

I would like to ask whether it is OK to count with the fact commands
such as:

	-export([t21/0, t22/0]).
	t21() ->
	    spawn(?MODULE, t22, []).

	t22() ->
	    io:format("DEBUG before~n"),
	    io:format("", [whatever]),
	    io:format("DEBUG after~n").

will spawn a new process that will block at its second statement.
That is, it will not print

	DEBUG after

?

Thanks for help,
Regards
