    Here is a guess, assuming that `channel->is_readable' has nothing
to do with the flags used to open the file descriptor in general
(because the GIOChannel probably has a `((channel)->flags & G_IO_IN)'
flag or something else for that purpose), maybe `g_io_channel_read_chars()'
assumes that there is data ready to be read at that point, maybe a boolean
variable was added to avoid performing a `poll'/`select' every time
g_io_channel_read_chars() gets called ?


Just a guess,
