(And I'm working to get a .git repository, CVS sucks... :-) )

The following are additions are up in CVS on SourceForge, and the 
documentation has been updated to match:

     Add -x (separate submits into chunks) and -X clones per dev

     When specifying a large number of asynchronous IOs, latencies can creep
     up because IOs are collected into large batches and submitted in one go
     via io_submit(2). This option will force the aiod to perform a 
series of
     io_submit calls instead. (The default is off, meaning that all 
available
     free IOs will be submitted in one call.)

     The -X option allows one to force aiod to split up a device (file) into
     <n> pieces, and has a separate process interact with each piece. This
     guarantees that the multiple processes stay out of each other's way
     (cutting down on multiple processes interacting with the same area of
     the disk).

     Added in -zz to seed random number generator

     With multiple 'z's we now seed the random number generator with the
     return value from time(2) at the start of the run.
