That may not be Ruby's fault entirely. In many cases, the size of memory 
chunks delivered by "malloc" and its friends is determined by the 
compiler or operating system. I've worked on systems where you got the 
next higher power of two, for example. If you asked for 5,000 you got 
8192, if you asked for 65 you got 128, etc. And many modern systems 
won't give you less than a physical page.

A physical page on most x86 operating systems is 4096 bytes, so 8 MB is 
2048 pages. There is also an option to run larger pages in Linux. What 
OS and architecture are you on?

P.S.: I'm cross-posting this to ruby-core -- that's where patches are 
discussed.
