Description changed by jdemeyer:
Old description:
> Under some circumstances, after doctesting, there remain ECL processes
> consuming more and more memory.
New description:
On some systems, when executing
{{{
./sage -tp --long devel/sage/sage/interfaces/lisp.py
}}}
there are two ECL processes which do (strace log)
{{{
read(0, "(setq sage0 2)\n", 1024) = 15
write(1, "\n", 1) = 1

write(1, ">", 1) = 1
write(1, " ", 1) = 1
read(0, 0x7f2c263b1000, 1024) = -1 EIO (Input/output error)
