capability to
writes output using a buffered writer. Disk writes are only done when the buffer is
full. So if an error happens during that write, data is potentially lost. In cases where
this is unacceptable, set $OMFileFlushOnTXEnd to on. Then, data is written at the end
of each transaction (for pre-v5 this means after <b>each</b> log message) and the usual
error recovery thus can handle write errors without data loss. Note that this option
severely reduces the effect of zip compression.</li>
