.SH "File descriptors, fork and ntlm_wb"
An application that uses libcurl and invokes `fork()` will get all file
descriptors duplicated in the child process, including the ones libcurl
created.
libcurl itself uses `fork()` and `execl()` if told to use the
`CURLAUTH_NTLM_WB` authentication method which then will invoke the helper
command in a child process with file descriptors duplicated. Make sure that
only the trusted and reliable helper program is invoked!
