I do not object to such a change (32 -> 1024 and perhaps 16 -> 64 or higher 
for the 'pause' case as well); however, it would be prudent to first test it 
against other usage scenarios. I can provide two test cases that would 
likely be affected, sp_atomic_mt_test.cpp and sp_atomic_mt2_test.cpp, and 
I'm sure that there are other Interprocess usage examples that can be 
checked.
