runtime: syscall_forkx on Solaris can return error on success
The syscall_forkx function returns the value of errno even on success. This can be a problem when using cgo where an atfork handler might be registered; if the atfork handler does something which causes errno to be set the caller of syscall_forkx can be misled into thinking the fork has failed. This causes the various exec functions in the runtime package to hang.
