Hi all,
I would like to remove some code which call methods which are rarely used.
Such methods are like follows:

        putenv(3), pread(2), pwrite(2)

I think that we should use just a natural method unless a special method has
a big merit for user. The reason is like follows:
o Method not used so much is risky, since such method is not often so tested.
  For example, we know the pread and pwrite in cygwin are buggy. Though it is
  not our business, user is not guilty.
o Reproduction of bugs becomes difficult, since it brings different results
  in different environments. For example, one system may use putenv() and 
  system use setenv().

What do you think?
Please tell me if I am wrong.
