Based on those examples, I suppose these variables can be made shared
variables (or rather: protected shared variables) declared in a package.
Then you can print from different processes to the same file. But still you
should be carefull not to open the file more than once.

Apart from everything, I don't like the idea of trying to mimic the C-style
print procedures in VHDL. This is my personal taste, based on the fact that
VHDL lacks variable argument lists. So there always be limitations. I'd
rather stick to VHDL and use type LINE from std.textio to build the strings
I want to print. Together with some home brew print procedures and
conversion functions things are quite manageable.
