[graphviz-interest] actual memory use of dot, fdp

For capacity planning, I'm attempting to get a general idea of how a) dot
and b) fdp handle memory on Linux.  Before diving into a tool like exmap or
valgrind to measure usage, maybe someone knows whether memory usage by dot
and fdp increases linearly with source file size, and whether it is some
semi-determinate multiple or fraction of the source file size.

I realize this may be a complex question given all the possible libraries
invoked.  Only xdot output is being generated.

Since we're in a multiuser server environment, simultaneous invocations may
differ, but maybe it's possible to make some estimate.

Also, I'm fantasizing a stream-based graphviz to which you could input one
or a few lines at a time but I'm assuming that it needs everything in
memory at once in order to do multiple passes for layout.
