When we rotate journals, we must set offline and close the current one, but don't generally need to wait for this to complete. Instead, we'll initiate an asynchronous offline via journal_file_set_offline(oldfile, false), and add the file to a per-server set of deferred closes to be closed later when they won't block. There's one complication however; journal_file_open() via journal_file_verify_header() assumes that any writable journal in the online state is the product of an unclean shutdown or other form of corruption. Thus there's a need for journal_file_open() to be aware of deferred closes and synchronize with their completion when opening preexisting journals for writing. To facilitate this the deferred closes set is supplied to the journal_file_open() function where the deferred closes may be closed synchronously before verifying the header in such circumstances.
