It's because the malloc() and new speeds differ by compiler.  If you're
really interested, there's an outdated article in WDJ April '97 that
compares malloc() and new speeds of several compilers: VC++ 4.2 was slowest,
Borland C++ 5.1 was faster, and Watcom C++ 10.6 and Symantec C++ 7.2 the
fastest.  Of course, these are all *old* compilers! :)

As John pointed out, you're not going to see much benefit (if any) when the
standard library contains a pool allocator itself (as does STLport and
glibc).
