[Bug libc/1128] Malloc not trimming filled-up sbrk space causes unnecessary system call overhead


------- Additional Comments From jp-www at dcs dot gla dot ac dot uk  2008-07-20 19:41 -------
I reported this bug about three years ago now, so my memory is a little bit hazy. However, I do remember 
that calls to free() were definitely causing expensive syscalls. I note the recent comments about sbrk(0) 
not being expensive due to caching and, reviewing the glibc sources, I have to agree with this. So I suspect  
there may be some detail missing from my original report that explains more what was going on.

Sorry!
