------- Comment #7 from Stefan Kost (gstreamer, gtkdoc dev)  2007-12-08 10:07 UTC -------
Okay, some more background. Its not about saving time as such. Its about
eliminating non-deterministic behaviour. When calling g_free() which calls
free() the libc allocator does trimming of the memory pool. Thus free() is not
always quick. When running a low-latency pipeline this could already cause
missing deadline. Bug 501239 has a proposal for allowing threads with
soft-realtime scheduling. There it is even more important to avoid malloc/free
calls.

I already explained why we don't want to use g_slice for most cases in
gstreamer in Comment #4. David, do you thing this wont apply?
