There's no PHP_PROJ involved.
With lsof I noticed that the mapfile remains in use twice or more by one
process.
But....in the malfunctioning situation I loaded php_mapscript.so through
php.ini
(using extension=php_mapscript.so);
After removing this line and loading mapscript with dl(php_mapscript.so)
everything works fine!
My next step will be to load MapScript.so through Apache directives,
stay tuned, 
results will be available after the weekend!
