Lacking any further clue as to what peculiarity might be responsible for
this weird behavior, I decided to simply let the nrpe process
permanently run under strace like
strace -f -q -e none -o /dev/null ...

The performance impact is minimal, and I finally get check results. Not
really a solution, but it'll do.

Cheers,
Flo
