sysmgr doesn't reap children processes

[biqqthiqq]

hey, so I've been running sysmgr for a while, I've noticed an issue where old runsyssv processes will not get reaped, and as these spawn pretty rapidly I end up hitting the process limit on my system and having to reboot.

  675 root      0:00 runsyssv /var/sysmgr/eudev
  676 root      0:00 runsyssv /var/sysmgr/dbus
  678 root      0:00 runsyssv /var/sysmgr/seatd
  910 root      0:00 runsyssv /var/sysmgr/dhcpcd
 3743 root      0:00 [runsyssv]
 3746 root      0:00 [runsyssv]
 3749 root      0:00 [runsyssv]
 3752 root      0:00 [runsyssv]
 3759 root      0:00 [runsyssv]
 3766 root      0:00 [runsyssv]
 ...

if we check these processes with pstree, it shows sysmgr as the parent process still, so init doesn't end up doing any reaping.

quick fix I found from 1 is adding a call signal SIGCHLD to sysmgr.c here,

	/* Go to the service directory and get all the service entries. */
	DIR *dir;
	struct dirent *ent;
        signal(SIGCHLD,SIG_IGN);
	while(1) {
		if ((dir = opendir(sysdir)) == NULL)

however not sure if this is the correct fix, I'm thinking it may be better add SIGCHLD to sv_signals, and add a condition to the term function to call wait if the signal is SIGCHLD, not too sure yet on how to gracefully implement though.
