OCCT 6.6.0: cutting 1600 cylinders from a box leads to out-of-memory on 32-bit system
Description
This issue is aimed to add a test case for performance of operation of running BOP on big amount of small objects, inspired by http://www.opencascade.org/org/forum/thread_12369/?forum=3
In OCCT 6.6.0, cutting 1600 cylinders from a box leads to out-of-memory on 32-bit system (Windows VC9).
On current master it works fine in less than 2 min

Dear abv, please give some details how is cutting performed:
are 1600 cylinders in one compound and only one BO operation is used or
cutting is performed one by one with help of 1600 operations?
are 1600 cylinders in one compound and only one BO operation is used or
cutting is performed one by one with help of 1600 operations?
Naturally single operation on 1600 cylinders is used.
I have pushed test script to branch CR24264 (test perf bop boxholes), please review
