>From SingleUnix:
The vfork() function will fail if:
[EAGAIN]
The system-wide limit on the total number of processes
under execution would be exceeded, or the system-imposed
limit on the total number of processes under execution by
a single user would be exceeded.
[ENOMEM]
There is insufficient swap space for the new process.
EAGAIN is the one you want, not EPERM.
