Can I make a IM Module resident?

[James Su <suzhe gnuchina org>]

Hi,
Recently, I'm developing a IM Module for gtk+-2.x, but I met a problem.
Because I registered a new class within my IM Module by
g_type_register_static, then when I open a input context the second
time, the application crashed. The error message shows can not register
a type which already registered. In order to solve this problem, I
realized that I must make my IM module resident in the memory to prevent
my class being registered twice.
I don't know if it's OK to use g_type_module_use within im_module_init
to make it resident? Or what else can I do to solve the problem?
