Subject: #defines in Ruby's .c files

I was talking to someone on irc who was trying to speed up sockets - he came up 
with a way to do it by modifying sysread() so that a new buffer doesn't always 
have to be allocated on each call. (sped up sockets by 314x by his account, BTW 
:)  However, he had to patch the Ruby source code to do this because he was not 
able to access a macro (READ_DATA_BUFFERED) from his extenstion code.  Turns 
out that the macro READ_DATA_BUFFERED is defined in io.c, so you can't use it 
from an extenstion.

So, I got to thinking that maybe #defines like that should go into .h files, 
not .c files (maybe it should be #define'd in rubyio.h) so that they are 
accessable in extenstions.

Would it be possible to move some of them to .h files for 1.8.5 (or at least 
before 2.0)?
