/* ---*** PORATABILITY WARNING! ***---
On some 64-bit compilers the array field must be 64-bit aligned when you plan
to access the data. You can write the data, but you may not be able
to read the data back out. In general, custom memory management is discouraged.
An alternate solution to this is to either use the standard malloc, or to specify
that array is a union of several large basic C types.
*/
/*
* UToolMemory is used for generic, custom memory management.
* It is allocated with enough space for count*size bytes starting
* at array.
* The array is declared with a union of large data types so
* that its base address is aligned for any types.
* If size is a multiple of a data type size, then such items
* can be safely allocated inside the array, at offsets that
* are themselves multiples of size.
