Yeah, correct, you lock up awesome with this code. It doesn't process new events
from the X11 server while lua code is running.
I guess you want something like this instead (untested):
local pid = awful.util.spawn("xclock")
local callback = function(c)
if c.pid ~= pid then return end
client.disconnect_signal("manage", callback)
wmnotify("hola")
end
client.connect_signal("manage", callback)
(However, this code doesn't handle any timeouts...)
Cheers,
Uli
