Comment:
Interesting suggestion. I will add the build option, but I would like other people's opinions if it should be the default.
I'm mainly packaging mimalloc to use with mold. Here is a benchmark of mold on my machine.
Benchmark # 1 uses mold with mimalloc in non-secure mode.
Benchmark # 2 uses mold with mimalloc in secure mode.
```
Benchmark #1: ../../link-test.sh
Time (mean ± σ): 255.3 ms ± 1.5 ms [User: 22.2 ms, System: 7.4 ms]
Range (min … max): 252.9 ms … 257.7 ms 20 runs
Benchmark #2: LD_LIBRARY_PATH=/tmp/mimalloc-secure/usr/lib ../../link-test.sh
Time (mean ± σ): 265.1 ms ± 1.7 ms [User: 26.8 ms, System: 8.1 ms]
Range (min … max): 261.7 ms … 267.6 ms 20 runs
Summary
'../../link-test.sh' ran
1.04 ± 0.01 times faster than 'LD_LIBRARY_PATH=/tmp/mimalloc-secure/usr/lib ../../link-test.sh', -3.7%
```
In relative terms, a 3-4% slowdown is significant, but in absolute terms, 10 ms is not something that I would notice. So I think I would be okay with making secure mode the default, even if I don't see the need for it in a linker.
(For interest, the same link command using GNU ld takes 1.9 s.)
