After further investigation it seems that while files are being copied in 
(using the put method) something (maybe KDirListerCache) really wants to 
update its directory list so a new slave is created after a while (normally 
after a few mkdir()'s have happened), the fist method to be called being 
listDir. This is possible as maxInstances is only a 'soft' limit. However 
then, I suppose as this second slave is now free, it starts creating 
directories, then files.

I have created a dummy IOSlave, that just shows an empty directory, and has 
a dummy mkdir and put method which do nothing. After copying in a large 
directory (arts CVS directory), 2 slaves were created both having their put 
methods called. However if I call exit() at the end of the listDir method 
if the slaves put method has never been called, the second slave terminates 
just after listing the directory, and is never re-created, so only one 
slave's put method is called, which is what I want. How can I do this 
without having exit() at the end of my listDir method? (which is a nasty 
hack)

Any ideas?
