Message:

VBoxService/Control Session: When creating a process for a guest session
the pipe file descriptor created for passing the secret key from the
session thread (pSessionThread->Thread = vgsvcGstCtrlSessionThread) to
its associated newly spawned process (pSessionThread->hProcess) isn't
closed when the session thread is closed down and destroyed thus leaking
the descriptor which can lead to the inability to run guest commands due
to too many open files (errno=EMFILE). ticketref:20902
