This might be helpful:

http://hg.dovecot.org/icecap/file/401c2bc71594/src/lib/child-wait.h
http://hg.dovecot.org/icecap/file/401c2bc71594/src/lib/child-wait.c

Idea would be that you'd have two child_waits, one for passdb and one  
for userdb. Then you'd add all the PIDs to that wait structure. I  
guess it should also have a plain child_wait_new() without a PID.
