exec and fixed buffer size

I am running into problems with exec() allocating a fixed buffer size for each array element that is returned. As such I am considering modifying it so that really sticks an entire line into each array value, not just the first 4095 bytes. What, outside of _Exec() do I have the potential to mess up by making this change? Was there a special reason for deciding that EXEC_INPUT_BUF should be 4096 other than thinking that it was big enough? In case it matters, this would be my first contribution to PHP3 development.
