Memory preallocation in python

[Marek Wojciechowski]

Hi,

i have a small problem in python. In case of matrix assembling -info says  
me something like:

[0] MatSetUpPreallocationWarning not preallocating matrix storage
[0] MatAssemblyEnd_SeqAIJMatrix size: 6006 X 6006; storage space: 12084  
unneeded,108036 used
[0] MatAssemblyEnd_SeqAIJNumber of mallocs during MatSetValues() is 6006
[0] MatAssemblyEnd_SeqAIJMaximum nonzeros in any row is 18
[0] Mat_CheckInodeFound 2002 nodes of 6006. Limit used: 5. Using Inode  
routines

This obviously means poor behavior because of dynamical memory allocation.
Unfortunately, I have no idea how to preallocate memory for Mat objects in  
python.
Any suggestions?

Greetings
