Does anyone know where the default buffer size for pipes (e.g. $ ulimit -p #) is defined and how it can be changed (or turned into a system tuneable) ? The current default of 5120 bytes is AFAIK not always optimal (originally defined when systems only had single-byte locales, with the rise of multibyte locales the number of _characters_ which can be buffered shrunk a lot) and a larger buffer size may be nice...
Some applications may misbehave or lock-up if the size of the pipe buffer is changed. It seems rather dangerous to change it system-wide.
