[zeromq-dev] pub sub memory leak problem

[david starkweather]

just came across an interesting result.  As noted from the previous
code,  valgrind did not detect any memory leak.  However, that was just
one message.  In this link,  there is code that loops through many
messages.  When I add the line at the end of the loop,  sleep(1), I can
run the code many times in a loop without any apparent memory leak.  But
wihout that line,  the memory quickly climbs.
