Title:
  ib_cursor_truncate commits transaction but doesn't release schema lock

Status in HailDB:
  Confirmed

Bug description:
  I've found that ib_cursor_truncate currently commits the transaction
  on success.

  from api0api.c: 
  /* This function currently commits the transaction 
  on success. */ 
  err = ddl_truncate_table(table, trx); 

  
  which isn't documented (except in the source :) 

  BUT, it doesn't release the schema lock... so unlike other DDL ops on
  success you have to release the schema lock yourself.

  it'd be great if ib_cursor_truncate() was a bit more consistent with
  the rest of the DDL api and the user called commit (which released the
  schema lock).
