See the attached file - against trunk, it creates 1000 codestrings in a
loop and throws them away. Here's the output:
{{{
@ START
TOTAL_MEM_ALLOC............: 262144
ACTIVE_PMCS................: 914
ACTIVE_BUFFERS.............: 218
TOTAL_PMCS.................: 1024

@ END

}}}
Note the ACTIVE_BUFFER output ; Looks like something is handing onto these
headers a bit too long, but running another sweep makes them go away?
