I will close this bug as "Invalid", because it is a feature of orm_memory 
objects to have a hard limit on the number of records they can hold.

If you see at server/bin/osv/orm.py:2030 (latest trunk, more or less), you 
will notice the "_max_count" member of the orm_memory objects. There is also a 
"_check_time" one that means the limit is only enforced every so many calls to 
self.create().

So, the absolute count of any orm_memory class is _max_count + _check_time -1
This, of course, applies to every class separately, not on aggregate.

If you need to have more data, define  a class like:

class my_bigmem(osv.osv_memory):
    _name = "foobar.big_mem"
    _max_count = 1000 # or more..

In such a case, I would challenge your design decision to use an orm_memory 
object for so many records. Why not a regular orm object after all? Memory 
ones are volatile, you know..

Title:
  Number of ressources in osv.osv_memory object

Status in OpenObject Server:
  Invalid

Bug description:
  On a wizard based on two osv.osv_memory objects with one2many relationship, i canno't create more than 211 lines in the "many" object.

I want to do a "pre" import of many csv lines into the osv.osv_memory object before validating in the wizard and do the actual import in an osv.osv object.

i made a simple scenario to check if it was a bug :

from osv import fields,osv

class test_school(osv.osv_memory):
    def _do_import(self, cr, uid, ids, context={}):
        myself=self.browse(cr, uid, ids, context)[0]
        for i in range(0,myself.size):
            self.pool.get("test.person").create(cr, uid, {
                "name":"Doe",
                "age":i,
                "school_id":myself.id
            })
        return True

    _name = "test.school"
    _columns = {
        "name":fields.char("name",size=20),
        "size":fields.integer("size"),
        "students":fields.one2many("test.person","school_id","students"),
    }
test_school()

class test_person(osv.osv_memory):
    _name = "test.person"
    _columns = {
        "name":fields.char("name",size=20),
        "age":fields.integer("age"),
        "school_id":fields.many2one("test.school","school",ondelete="cascade"),
    }
test_person()

This is a silly example but you can make tests with size over 211 : the number of lines will remains 211 (sometimes 201...) and only the last added lines will remain in the table...
