I will consider adding a BYEIGHT section of code to crc32.c.

Darn.  That's really the only code that matters for the speed of  
compression.

That's on my to-do list, but it's not high priority.

I don't have a windows system, so I can't do it.  All of the pthread  
calls are isolated in yarn.c for just this reason.  All someone would  
need to do is write a different yarn.c that uses windows' native  
thread functions.
