*************************** DESCRIPTION ***********************************
|
|
|
|
The class is specific to hc, and is designed to prevent the creation of
|
|
temporary files by using global memory instead. Writing to the file will
|
|
copy the data to memory until the total amount of data exceeds a reasonable
|
|
size, at which point a temporary file will be created and all data from
|
|
that point on will be written to the temporary file. Since the compiler
|
|
tends to generate oodles of small temporary files, this should reduce or
|
|
eliminate the actual number of temporary files.
