/* This abstraction allows logging to files. The lines are logged as they are
* given, without timestamp or other information. A global list of all log
* files is kept in order to provide a mechanism to re-open all logs (on
* SIGHUP, for example).
*
* These functions are not thread-safe. I/O errors are silently ignored. :-(
*
* TODO: Currently, logfile_log() flushes each line to the OS before returning.
* This is required if you don't want to lose lines in the case of a crash, but
* hinders performance if losing the very last entries is acceptable, for
* example with chat logs. An interface should be added to allow deferred
* flushing of the log entries.
