[IMP-dev] ObjectContainer disabling checks

[Daniel Russel <>]

I had missed wrapping one of the checks in ObjectContainer with NDEBUG  
which made adding large numbers of particles painfully slow.

I can't submit a patch since it would conflict with the not yet  
committed changes. It is simple, the single object insert needs to  
have its check wrapped with
    IMP_BEGIN_CHECK(EXPENSIVE);
    IMP_END_CHECK

And the multipartcle check which is currently CHEAP should be made  
EXPENSIVE.
