This avoids creating a PathParser to use them, which allocates memory that won't be used.

continuous-integration/drone/push Build is passing
This can cover the entire address space at once in a more memory-efficient way.
Stress-tested using 'base64 /bin/ls' which allocates enough contiguous
virtual memory to store the entirety of /bin/ls :)
A couple of bugs and fixes later, here we are!
