Yeah, that was the idea.

You need to find a pointer to BrowserWindow and pass it to 
a_UIcmd_reload(). Check a_Bw_num() and a_Bw_get() in src/bw.c.

We should reload the current page on all windows.

I'm not sure if we can do this from the context of a signal, we probably 
need to register a timeout in FLTK and handle it from there.

Probably not a very easy issue. I should start labeling the ones that 
are easy.

Best,
Rodrigo.
