+ |                              DESCRIPTION                                   |
+ The file-writing interface is streamy, but behind the scenes the data just
+ accumulates in memory and gets written to the fs when the stream is closed.
+ Now that we have the strings table to accumulate the data, we no longer
+ need to hold it in memory (although note that the issue of cleaning out
+ unreferenced strings after a crash, or even after a writer just wanders off
+ without ever closing the stream, is tricky).
+
