use fork server in executor
...
This avoids exec per test.
Also allows to pre-map shared memory regions.
And will allow to pre-map coverage regions, etc.
Seems to work already, but probably there are still some bugs.

open /proc/cover only once in executor
...
First, it is just not necessary to open it multiple times.
But more importantly a program can close fds that it previosuly used:
r0 = open(...)
close(r0)
close(r0)
and this can close cover fds created in threaded mode.
