I'm noticing these console messages when starting up a fresh Squeak4.2-10548-alpha.image on Cog.app 4.0.0 from http://www.mirandabanda.org/files/Cog/VM/VM.r2316/ on MacOS X 10.6.5

Are the messages anythig to worry about? Ken G. Brown
These require a change to the VM, something about calculating the start & length of the mprotect arguments correctly.

yep. i tried to play with these arguments by rounding them , but no positive change.
the one problem that when reading an image, vm requests to allocate unaligned block of memory, and even worse than that, it does not remembers the exact size of allocated memory. So, it is hard to pass exactly the same values to mprotect() , for clean experiment, to see if it works at all, or there just something weird with that function.
