FreeBSD: enable dlmalloc by default (--enable-malloc-replacement)
* After re-benchmarking the performance, I in fact detected a 20-25% speedup if
memory limiting is active. Both using `time` and the builtin monotic timer ::^B.
When memory limiting is disabled, there is no detectable difference to jemalloc.
The following test case was used:
sciteco -e '::^BUs 100000<@^U[^E\a]"^E\a" %a> ::^B-Qs='
* I also played around with getrusage(), but it doesn't seem to be a viable
API for detecting the currently used RSS, i.e. it does not allow recovering
from OOMs.
