pcntl - class callbacks

Attached is a fully tested patch for class based callbacks on pcntl_signal .. the appear only to work if you build pcntl into php, not as a module.. the only problem i have with it however is the leaking of memory.. - any hints would be nice.. 511 is the zval_copy_ctor(handle_copy); line.... /usr/src/php/php4/Zend/zend_execute.c(1694) : Freeing 0x08223360 (12 bytes), script=test-pcntl2.php Last leak repeated 1 time /usr/src/php/php4/Zend/zend_API.c(1355) : Freeing 0x08223318 (21 bytes), script=test-pcntl2.php Last leak repeated 3 times /usr/src/php/php4/Zend/zend_hash.c(178) : Freeing 0x082232C8 (32 bytes), script=test-pcntl2.php Last leak repeated 3 times /usr/src/php/php4/Zend/zend_hash.c(406) : Freeing 0x082231E8 (35 bytes), script=test-pcntl2.php Last leak repeated 3 times /usr/src/php/php4/Zend/zend_execute_API.c(413) : Freeing 0x08223038 (12 bytes), script=test-pcntl2.php Last leak repeated 3 times /usr/src/php/php4/Zend/zend_execute.c(2001) : Freeing 0x08222EE0 (13 bytes), script=test-pcntl2.php /usr/src/php/php4/Zend/zend_variables.c(106) : Actual location (location was relayed) Last leak repeated 1 time /usr/src/php/php4/Zend/zend_execute.c(1998) : Freeing 0x08222EA0 (12 bytes), script=test-pcntl2.php Last leak repeated 1 time /usr/src/php/php4/ext/pcntl/pcntl.c(511) : Freeing 0x08222378 (44 bytes), script=test-pcntl2.php /usr/src/php/php4/Zend/zend_variables.c(117) : Actual location (location was relayed) Last leak repeated 1 time
