Not unless your program is leaking.

No, it's the total bytes you currently have allocated.

self - number of allocated directly from function
current - number of bytes allocated from function and children

Nothing is cumulative.

This is on the web page :-)  http://www.gnome.org/projects/memprof/

It means Pango thinks someone tried to free a block of memory that 
is not allocated. If your program isn't crashing without memprof
it's probably memprof not quite working right on your system /
with your program. 

All output to the console is debugging output - if everything is
working 100% correctly, there shouldn't be anything there.

Sorry, no docs. (That's the other thing in the FAQ section on
the web page.)
