I used a function and get the following results.

int
myvalign(int x) {
  return x & pageMask;
}

 int argToAlign = oldLimit - heap + delta;
      int align = myvalign(argToAlign);
      int newSize= min(align, heapLimit);
      int newDelta= newSize - heapSize;

oldLimit=0x7929cfe8
delta=0
newSize=23293952
newDelta=-4096
align=23293952
argToAlign=23298024
heap=2009485312
heapLimit=1073741824
squeak: /tmp/squeak-svn/platforms/unix/vm/sqUnixMemory.c:181:
