<div style="">
<p dir="auto">What's the purpose of this check and returning <code>NULL</code>? <code>system_priority_file</code> is set early and guarded by <code>global_init_mutex</code>, so, without locking, this makes it a "filename of the system wide configuration loaded or currently being loaded by the library; NULL if loading hasn't been attempted yet". Lock and turn into "filename of loaded; NULL if not yet"? Stop returning NULL?</p>
