I thought that was fixed a long time ago: (cvs log proc.c)
revision 1.34

Prevent fd exhaustion in the parent when loading the listening server
sockets by sending the fd one-by-one. This allows to start httpd with
max 32 server instances and many server sockets without changing the
default rlimits in any way.

revision 1.33

Modify httpd(8)'s proc.c to use less file descriptors during the daemon
start up. To achieve this proc_init() initiates only the necessary pipes
between child and parent, allocate and distribute fds in proc_connect().
In case of configuration checks ('-n') we do nothing in proc_init() and
proc_connect().
