[Bro-Dev] #574: More exessive memory usage

[Gilbert Clark]

I've been thinking about building a library interposer (in the spirit of 
http://developers.sun.com/solaris/articles/lib_interposers.html) that 
will track malloc / realloc / calloc by script line (pull the top frame 
out of g_frame_stack) and script file; I envision using SIGUSR1 and 
SIGUSR2 to dump and clear gathered statistics, respectively.

I tried to do something similar with systemtap, but I wasn't able to 
keep bro running fast enough to process nontrivial volumes of live 
traffic.  Haven't tried dtrace yet.

If this sounds like something that'd be useful here, I can inject it 
into the top of the TODO.
