I still experience this on Ubuntu Hardy, 
PHP 5.2.4-2ubuntu5 with Suhosin-Patch 0.9.6.2 (cgi-fcgi), so this
should be reopened.

Workaround: Kill those lurking process regularily using a cronjob.
This works for me (Ubuntu Dapper, PHP 5.1.2 (cgi-fcgi) (built: Jul 17
2007 17:21:59) ), you probably need pkill -9 .

#/bin/bash
pkill -f -x /usr/lib/cgi-bin/php -P 1

The problem is that this bug affects Debian's PHP5 package of etch[1]
and in order to fix it the right patch is required. We can't simply
'update' the source package.

Comment from ondrej@sury.org : 

I don't believe that this patch could correct blocking I/O.

What this patch does is just remove one extra memory pointer which was
not needed.
 
Correct fix would be to use O_NONBLOCK when opening file descriptor
and
then test for EAGAIN.  Or use select(2) before reading from descriptor
in safe_read() function to test if data is available for reading.

I could be wrong, but it just doesn't seems to be fix for this problem.
