Thanks, Matt. I'm not sure whether the problem was in OpenSSL, but it was definitely in PHP. I installed 5.4 and the LA immediately dropped to reasonable figures. PHP packaged in php5 even includes php-fpm and I didn't have to compile it myself. So, I think I must have done something wrong when compiling it. Still trying to pinpoint the real problem...
