[MLton-devel] mlton on freebsd

Hi Sam.  Yep, I remember trying to convince you to use MLton and its
fast threads for http proxying.  :-)  I'd be interested to hear if
you're thinking of using it for something now.

We've had a couple inquiries lately about FreeBSD.  Here's a couple of
mail threads.

But as the mail archive shows, the previous patches didn't pass all
the regressions and didn't self compile.  A previous mailer also had a
problem -- his machine has only 700M.  We don't understand the memory
problems.  It should take the same amount of memory to compile on
FreeBSD as on linux -- and we compile all the time on machines with
only 512M.  In fact, the latest experimental release of MLton can self
compile on machines with 256M of ram.

Sure.  Please send us the patches and we'll take a look.  We've
already checked in some of the patches that Michael Neumann sent,
which he said at least allowed the runtime compile.  If you want to
look, see the 20020825 release or the CVS.  Maybe you took a similar
approach?

There must be some other problem -- maybe a difference in the behavior
of mmap?
