As far as I know, this behaviour should not be affected by overcommit as
the unused pages are all mapped with PROT_NONE and thus do not count
towards the commit limit as they cannot be used without the mapping being
changed. `ulimit -v` (aka RLIMIT_AS) however limits the actual address
space size, and so this does count towards that (as do mmap()ed files and
other such virtual mappings that do not count towards the commit limit).

I, too, found this change a bit problematic btw: It means I can no longer run Haskell on systems where memory overcommit is disabled.
For example, I used to run my shell with an appropriate `ulimit -v` to guarantee that a single program can't force me into swapping; I can no longer do that. _______________________________________________ Haskell-Cafe mailing list To (un)subscribe, modify options or view archives go to: http://mail.haskell.org/cgi-bin/mailman/listinfo/haskell-cafe Only members subscribed via the mailman list are allowed to post.
