After considerable effort I discovered what seems like a leak caused by repeatedly "do"ing n file that reads from it's DATA handle. Closing it stops the leak.

Is this a known problem? 

$ perl -nwe 'BEGIN {print "$$\n"} do "file_with_DATA.pl"'
$ head -n 10 file_with_DATA.pl 
() = <DATA>;
#close(DATA);
1;
__DATA__
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
[... Many more lines of "AAAA"s ...]

Update:
p5pmsg Potential to leak DATA filehandles
man perldata:
The filehandle is left open pointing to the contents after __DATA__. It is the program's responsibility to "close DATA" when it is done reading from it.

In reply to do + <DATA> = leak by bsb
