   Ah, no it was caused by the PR, because it changed 
`DEFAULT_MAX_ROW_GROUP_LENGTH`, which doesn't set the _default_ `chunksize`, 
but actually caps the max chunk (row group) size regardless of the 
user-specified `chunk_size`.
   
   It seems this constant is used both for setting this max upper cap, and as 
the default values for `chunk_size` in `WriteTable`. I assume we will have to 
distinguish those two meanings?
