Forks a child process, closes parent file descriptors as appropriate in the\n\
child and dups the few that are needed before calling exec() in the child\n\
process.\n\

The preexec_fn, if supplied, will be called immediately before exec.\n\
If close_fds is true, close file descriptors 3 and higher, except those listed\n\
in the sorted tuple pass_fds.\n\
\n\
The preexec_fn, if supplied, will be called immediately before closing file\n\
descriptors and exec.\n\
WARNING: preexec_fn is NOT SAFE if your application uses threads.\n\
It may trigger infrequent, difficult to debug deadlocks.\n\
