O holiest monks of perl,

I am processing a substantially large amount of data which contains things containing nested {{}} that are completely irrevelant to me. All I need to do is find them and remove them, only I need to do this several billion times on arbitrarily large (did I mention large?) strings. The following works flawlessly:

my (@array) = $text=~m/( \{\{ (?: [^\{\}]* | (?1) )* \}\} )/xg;
$text=~s/\Q$_\E/ / foreach @array;

...up until a certain point at which, I imagine, the machine runs out of memory since it is memoizing this regex. The problem with that is that the things in {{}} occur so infrequently that memoization is actually hurting here, not helping.

Is there conceivably a more efficient way to do this? Please tell me there is and I've been going about Googling for it the wrong way. :)

TIA, DMN
