Subject: DJGPP v2.01 malloc wasting 4Kb

Hi All:

 If I'm right malloc is wasting 4Kb each time we allocate a block >= 4Kb. 
Malloc allocates one extra page and this page is simply wasted. I saw it when I 
tried to allocate all the RAM in pages (after configuring CWSDPMI to allow it 
because I were using 32Mb). 
 My questions are:

1) Is that correct? (To test it you can make some allocations of 4000 bytes and 
check the free memory you'll see each allocation is taking 2 pages instead of 
1).
2) Can we fix it in the distribution? Currently there are too much known bugs 
in v2.01, as an example: my editor needs at least 3 patchs for libs to work.
3) What's the status of 2.02? The last snapshot is too old!

I know Nate is mainting an unofficial patched version but: Are these patchs 
really tested? isn't that worst than having an updated beta version?
