The default value of 16 is insufficient on heavily loaded machines (particularly SMP machines), and if it is exceeded then executing further processes will generate a SIGABRT. This is a workaround until a better solution can be implemented.

(Bad explanation provided by me.) From me: Rework pipespace accounting code to handle this new layout, and adjust our default values to account for the fact that we now have a solid limit on allocations. Also, remove the "maxpipes" limit, as it no longer has a purpose. (The limit on kva usage solves the problem of having two many pipes.)
