Using the sysvshm extension I am not able to define a memory size different from 
the default 10000 bytes.
The second parameter '$memsize' of shm_attach() is ignored (but throws a warning 
about an invalid key).
Setting 'sysvshm.init_mem' to something else than 10000 has no effect as php 
doesn't recognize it as a valid config option. ini_get() on said config option 
returns 'does not exist'.
I even tried changing the hardcoded '10000' value in sysvshm.c to something 
different and recompile php, which didn't have an effect either.
