allocate directly in gen2, fixes 14-while.t
declaration before code, really
revert a revert, we an run this code now
return is a list prefix
added MVM_proc_spawn function
got a basically working MVM_proc_spawn(hopefully)
added env to MVM_proc_spawn
free _env after spawn
added env to spawn actually
avoids a warning
bug fix, diakopter++
Add MVM_platform_sleep()

The function tries to guarantee a delay of at least
the requested amount of time.

The nanosecond resolution is somehwat 'optimistic', but
so is the POSIX API it wraps.
Implement proper nqp::sleep() and keep current version as nqp::microsleep()
update sleep as per discuss in #perl6
fixed test after new sleep
Merge branch 'master' into nobank
