It also does not explain why SIGQUIT won't work (it is not blocked, I made my app print out the whole signal mask and SIGQUIT is not blocked), but since we don't use it anyway, this might be an entirely different bug and should maybe be ignored for this issues.

It could be that SIGQUIT is being ignored; if the signal is ignored it will be silently discarded rather than appear in the blocked or pending signal lists.

I'd tell you to use "ps -O ignored," which is documented but apparently
doesn't actually work:

$ ps -O ignored
ps: sigignore: keyword not found

so the next easiest thing would be to use sigaction(2) to get the previous
disposition of SIGQUIT for your daemon and check to see if its handler is
set to SIG_IGN.
