New Comment:
with the ob_end_clean call in my code my intention is to discard the
buffer and disable output buffering. i do not have any ob_flush calls
in my code.
here is some background on what i'm trying to do. in a nutshell i have
a call in my code (dio_fcntl) which attempts to get an exclusive lock
on a file. in theory this call can block forever (or until the script
execution timeout occurs). to alert the user that a timeout occurred
while waiting on the lock i create a buffer with an error message just
before the call to the code that may block. if the script gets the
lock before a timeout occurs i call ob_end_clean() to release the error
message in the buffer which is not needed. if a timeout occurs php
flushes this buffer containing the error message and the user is
notified of the error.
the purpose of registering a callback in my case is not to modify the
output buffer (the error message) but to put a message in the web
server error log that this problem occurred. i was expecting the
callback function to not get called when ob_end_clean() is executed.
in theory the callback should only be called in my case if the script
execution timer expires.
some code which can block

I guess you have some ob_flush() functions, don't you?

i have the following code where ... represents some
echo statements but does not include any ob_xxx calls.
ob_start("func");
...
ob_end_clean();
and func is defined as:
function func ($buf) {
error_log("got here",0);
return $buf;
}
when this code runs i get "got here" in my error log.
i am expecting the ob_end_clean call to turn off output
buffering which includes not calling the callback I
registered. i am using 4.2.0rc2 currently.
