Right. But what prevents anybody to have a hacked, non-testing, ld.so lying

Having "noexec" on every user-writable mount can
kind of make that difficult - you can't easily run
the ld.so you just copied in.

It just can't do them (reliably at least) in general.
Certainly it can't, now and then.
Right now the check is to see whether the mmap(PROT_EXEC)
fails. I wanted to change that to something that at least
won't break other apps, but of course without adding any
extra reliability.
