[DotGNU]question about ArrayList.cs

[Ian Fung]

in the Realloc function, making the new array for more elements looks like
this:

int newCapacity = (((count + n) + 31) & ~31);

I assume the + 31 and & ~31 is some hack. I was just wondering why it needed
to be there. is it something about bits being in the right place cause the
way IL works etcetc? just wondering.

thx
