Re: Let's use the STL! [Was: about the abstractData.h]

The problem with the STL is that the performance of these libraries is
truly horrible. The approach that is currently planned is to attempt to
provide very similar functionality - just with some good performance. It is
expected that the STL will replace these libraries when it grows up.

There are a number of places where these standard, industry-wide standards
just do not live up to the kind of performance that is expected. With each
new technology, we take a significant performance hit.

When we first started using vxWorks we found that their locking semaphores
used 75 usecs even when the semaphore was available. Our rewritten one took
3 usecs when the semaphore was available. It took one small design meeting
about 4 hours to design the code and prove that it was safe. It was worth it.
