           Summary: suEXEC and low RLimitMem gives "crit: invalid uid"

Using the same httpd.conf and file system from a httpd-2.2.9 install under an
old 32-bit slackware and moving to httpd-2.2.12 under slackware64, VHosts with
"RLimitMem 10000000 15000000" stopped running CGIs, each CGI issuing
"[2009-08-22 09:48:46]: crit: invalid uid: (80)" to suexec_log  VHosts with a
higher RLimitMem function as normal.  (Filed under 2.2.13 because it does the
same under the current release)

For clarity, 80 is a valid UID, adding:

else {log_err("uid ok - (%d)\n",uid);}

after the clause produced "[2009-08-22 09:02:22]: uid ok - (80)" for VHosts
with a higher RLimitCPU set, and ran the CGIs as expected

Removing exit(112) from support/suexec.c and reinstalling didn't stop the CGIs
from failing.  No errors in any files pointed to a process being reaped due to
memory constraints, under the shipped code or my debugging modifications.

Increasing to RLimitMem 50000000 75000000 seems to work fine for now.
