+ Iternally they are mapped into the entries with the number of bytes
+ equal to the power of 2. The smallest entry size is 8 bytes. The
+ next one is 16 bytes etc. So, if the user requests 6 bytes, he gets
+ 8 byte entry. If we asks for 25 bytes, he gets 32 byte entry etc.
+ The input parameters "nSteps" says how many fixed memory managers
+ are employed internally. Calling this procedure with nSteps equal
+ to 10 results in 10 hierarchically arranged internal memory managers,
+ which can allocate up to 4096 (1Kb) entries. Requests for larger
+ entries are handed over to malloc() and then free()ed.]
