the free you are looking at is not a  good indication of 'actual  
memory available' in linux.

the number you are intersted is this one:

> -/+ buffers/cache:         46        960

vs

> -/+ buffers/cache:         44        962

before execution you had 960 available for use by applications
after execution you had 962 available.

here is one of many pages explaining memory under linux:
