Can you explain this better?

For example, we use this in codes:

+    qemu_chr_add_handlers(s->chr_sec_in, compare_chr_can_read,
+                          compare_sec_chr_in, NULL, s);

when data come to s->chr_sec_in ,we want to make
compare_sec_chr_in() run in another thread rather
than main loop.

But qemu_chr_add_handlers() can only
work for global default context other than thread default context.
So we use g_souce_attach(xx, g_main_context_get_thread_default())
replace g_source_attach(xx, NULL) to attach g_source.
