*shrug* OK.

Find attached a version that does the equivalent of local %SIG for
each pl/perl(u) call. I was only able to test on 5.14.1, but I looked
at 5.8.9 to make sure it looks like it works.

Its a tad slower (something like 0.00037ms per call), but uhh thats
quite acceptable IMHO (best of 5 runs):

=> create or replace function simple() returns void as $$ $$ language plperl;
CREATE FUNCTION

-- pre patch
=> select count(simple()) from generate_series(1, 10000000);
Time: 10219.149 ms

-- patched
=> select count(simple()) from generate_series(1, 10000000);
Time: 13924.025 ms

Thoughts?
