Orion Hodson commented on ZOOKEEPER-1933:
-----------------------------------------

[~fpj] This compiles fine here on Windows. Need to get tests lit up on Windows, 
but haven't started trying to find a solution for this yet.

I might be tempted to tweak the patch slightly:

- move the loop_count (io_ticks?) as a counter into the _zhandle struct and 
have it increment in do_io() unconditionally.
- change the counter to be volatile.
- change the test to only read the count value and look at the number of 
io_ticks elapsed during the test.
