We can't do it this way. pdfork() is used there to prevent killing only
one process. If we use fork() and we kill parent process the second
process (child process) will become a zombie process. I suggest to
revert this change. The changes that Pawel commit (r254486 (thx
jilles!!!) and r254480) should resolve all problems.
Cheers,
oshogbo
