This may be a bug.  Initially it's a question:  Should a crosstab control be able to handle any amount of data?  I've included a simple report with a scripted dataset that feeds a crosstab and parameters to determine the number of rows and columns.  It's easy to get a OutOfMemory exception by setting the rows and columns high enough.  In my test I used 3000 columns and 150 rows.  I'm using a small tester program that uses RunTask only.  -Xmx=1024m, -XX:MaxPermSize=256m. 

Reproducible: Always

Steps to Reproduce:
Run the attached report using IRunTask with Rows=150 and Columns=3000.  In my test it runs out of memory after 183000 cells.
