Milter-greylist

All;
  I am having a problem wherein I max out at 255(6) children from
milter-greylist. This is causing an issue, as sendmail attempts to open a
pipe to a child, and the milter can not spawn a new child for it to connect
to. As such, the milter fails for that message. I am running rh73, and have
confirmed that neither sysctl nor ulimit are at fault here (max proc for
milter user, 512, max FD open, 2048). I could find nothing that would
indicate a hard limit on this. Is it possible to increase the max conf
children from 1 to 2 as a psuedo fix for this, enabling more children? What
would the effects of this be? I understand that this is an issue on pre-nptl
linux machines. Any assistance would be appreciated.

For reference, a pstree output looks like:
 |-milter-greylist,19703,milter)
 |
  |   `-milter-greylist,19704)
  |
  |       |-milter-greylist,(255 children here at max sendmail connects)

I would think that increasing conf children to 2 would create an additional
milter at 19705, with 255 max children allocatable to it as well. If this is
inaccurate or dangerous, let me know. Thanks.
