Well, _SC_CHILD_MAX is documented across platforms as:
Heck, even POSIX specifies CHILD_MAX as:
"Maximum number of simultaneous processes per real user ID."
Also, one Linux machine actually shows the _SC_CHILD_MAX value equal to

When /dev/fd is missing, and named pipes are used instead (like on AIX),
this snippet sometimes does work right, wrong, or hang - depending on
the operating system's process scheduler timing:

Sounds like you've run into this problem (patch available):
http://lists.gnu.org/archive/html/bug-bash/2013-10/msg00114.html

Fix: (patch attached)
builtins/common.c:
Do not depend on getcwd() doing buffer allocation.
config-bot.h:
Ignore GETCWD_BROKEN, keep HAVE_GETCWD as is.
Additionally, the check for GETCWD_BROKEN can be dropped
from configure.in and aclocal.m4.
Thanks!
