I think the practical limit is based on the amount of memory allocated to each TMM. You can check this by running tmstat from the CLI and seeing how much memory is allocated to one TMM:

 

 

Memory Allocated

 

33,777,728 / 1,814,036,480

 

 

4Kb x 1 million is still 3.8 Gb. On an 8900, each TMM has ~1.8Gb of memory available.
