I have already done this, but there are other reasons for host list
randomization. Suppose that more than one person is using the compile
farm, and that all users have the same hosts file. If the number of
distccds is higher than the number of parallizable (?) tasks in a build
(say N), them the first N machines get hit very often while the others are
seldomly used. Host list randomization would fix that problem.

I thought about that, but the thing is that the computer labs are used by
students during the day. Most of them prefer Windows (alas!), so your
suggestion about using Cygwin could just work. On the other hand, I do my
big compiles (KDE and the like) during the night-time, when the computer
labs are used for scientific calculations (under Gentoo). For my daytime
work, it is sufficient if the 2-way server and several other machines
across the lab are available.

Great to hear that! Have fun with one of the easiest languages to learn

But back to the initial question: will these patches be merged into the
main path of development? It would be really a great step forward. May I
directly ask the maintainer of the package what he thinks about the two

Thanks and best regards!
