Yes, for any <exec> type of task on Windows (this includes, for example,
<attrib>) that used to take way less than a second.

Currently each such <exec> takes at least a second (give or take a few
millis) so if you are using a lot of little <exec>s this will sum up.

The reason behind this is that Ant 1.7.1's logic could make processes
hang on Windows and the revised logic involves timed joins to simulate
async reads.  We may get through with making the sleep interval a little
bit smaller in future versions - or we may find a better fix for
