It used to be safe to assume that anyone running mod_perl had a
bottleneck on memory and the number of processes they can run.  This
isn't always true anymore.  Some people have plenty of headroom for
mod_perl processes but can't allow frequent access to a shared
resource like a fragile database.

The request pnotes is commonly used to pass information between
handlers in different phases.  I haven't seen much use of the
connection pnotes.
