I enclosed the USRSTACK definition in that file in a "#ifndef -
#endif"-bracket and set the value in the kernel config file, thus keeping
track of my changes.

Thanks a lot, that worked fine.


I doubled USRSTACK to 0x1c000000, set MAXDSIZ to 256M and NKMEMCLUSTERS to
768.

The max data size limit was then 256 MBytes and I was able to execute xv
"Algorithms" on a 4kx3k image; the xv task was shown by top to be 203 MB.
