---------------------------+------------------
 In imfs_initsupp.c, there is code to limit the maximum block size for the
 IMFS to a power of two <= 512. This code was written a long time ago (at
 least 15 years) and at that point having a lot of RAM was inconceivable. I
 am proposing to increase the limit to at least 8192.

 I am not proposing we change the default which is currently 128 bytes.
 This gives a maximum file size of ~1GB.

 Increasing it to 8192 would make the limit approximately 16GB.
