  1. When a TAP file has non-zero exit status, retain temporary directories.

  2. Fix running out of file descriptors for spill files.

  3. Track statistics for spilling of changes from ReorderBuffer.

  4. Handle ReadFile() EOF correctly on Windows.

  5. Add logical_decoding_work_mem to limit ReorderBuffer memory usage.

  6. Generational memory allocator

  7. Support retaining data dirs on successful TAP tests

One thing I don't understand (besides, apparently, the documentation):
how did this problem escape detection by check-world for such a long
time?  Surely we expect to hit the end of various temporary files in
various tests.  Is it intermittent, or dependent on Windows version,
or something like that?
