ManagedMemoryDataSource with large maxCached hang

This is a strange bug that I found while working with large attachments that I 
did not want written to disk. Here is what is happening:

After creating a data handler by passing in a ManagedMemoryDataSource with a 
large maxCached amount, say 1 megabyte, and subsequently calling 
dataHandler.getName() - down the line when the SOAP call is invoked Axis hangs. 
At first I thought the problem was simply that ManagedMemeoryDataSource was not 
handling large maxCached sizes. But after investigating the code for a while I 
did not think that was the case. Something strange is going on, as commenting 
out dataHandler.getName() fixes the problem.

I no loner need to call dataHandler.getName() since I don't have to manually 
delete the temp files anymore since I was able to up the maxCached size. Still, 
this problem causes call.invoke() to completely hang so it should be fixed.
