[xml] leak in globals.c

[Prashant R <ramapra gmail com>]

void xmlInitGlobals(void)

{

    xmlThrDefMutex = xmlNewMutex();

}

This function is called multiple times and new allocation occurs each time . 

is this fixed or going to be a part of the next release ? 

I searced the bug database , but couldnt find anything specific to this.

Thanks
