g_thread_init

This afternoon I spent almost two hours hunting a memory leak reported by valgrind. It said that there are 2034 bytes definitely lost in g_hash_table_new_full(), but I am pretty sure that g_hash_table_destroy() is invoked with each key been passed to g_free().

The fix turned out to be a slight modification of call sequence to g_thread_init(), from:

1. create hash table
2. add hash entry
3. g_thread_init()
4. reclaim hash table

to:

1. g_thread_init()
2. create hash table
3. add hash entry
4. reclaim hash table
   

then, the error memory leak error just vanished.
