This is very nice! I was shocked and puzzled when I found the GNU libc
allocator didn't release VM back to the OS, it's great to confirm you
guys are (IMHO ;-) more sane than the gcc and libc folks :-)

Yes, but not all of it since that causes extreme slowdowns in certain
cases (due to constant freeing and reallocating memory to/from the OS).

Yes, but it keeps always one block to avoid repeated allocating/releasing.

There is code I saw that seems to work great using:
SetLength(MyArray,100);
Which allows MyArray[100]:='Some ansiString';
Dynamic arrays start at index 0 up to Length-1, so actually this code would
corrupt memory ;) (but I assume this is

Both are ok.

That is your problem. To optimize performance, nearly all me
Hello All.
I saw a great example of using:
MyArray: Array of ansistring;
There is code I saw that seems to work great using:
SetLength(MyArray,100);
Which allows MyArray[100]:='Some ansiString';
What I don't know is how to clean this up.
Making all the 100 ansistrings in this example set
