OK, I'll break down into these categories:
{w/,w/o}us: {with, without} the above usleep() patch
p-x.y.z: with php version x.y.z
w/o us + p-5.1.6 (from CentOS 5.4) : works.
w/o us + p-5.2.10 (for RHEL5 'remi') : works. [*]
w/o us + p-5.2.11 (/usr/local/bin/php) : sometime does sometime doesn't.
w/o us + p-5.3.0-2 (for RHEL5 'remi') : works [*]
w/o us + p-5.3.1-1 (for RHEL5 'remi') : does not work, segfaults. [*,+]
(a complete make distclean was done before compiling w/us - may not
have been needed)
w/us + p-5.1.6 (from CentOS 5.4) : works.
w/us + p-5.2.10 (for RHEL5 'remi') : works. [*]
w/us + p-5.2.11 (/usr/local/bin/php) : sometime does sometime doesn't.
w/us + p-5.3.0-2 (for RHEL5 'remi') : works [*]
w/us + p-5.3.1-1 (for RHEL5 'remi') : does not work, segfaults. [*,-]
The usleep line does not seem to have any effect. I didn't collect
full debug outputs.
Our dept will update to 2.10.1 soon, so for the time being (or may be
even for long) I'll stick with one of the working phps, we can debug
later.
Regards,

[*] I am not sure what this 'remi' thing is, anyway, the php-cli
(x86_64 versions) packages used were obtained from here (searching for
php-cli and checking only RHEL5 and CentOS 5):

[+] segfaults with:

*** caught segfault ***

[-] segfaults with:
