Look under "zombie" in the manpage:

: zombie [keys]
: defzombie [keys]
: Per  default screen windows are removed from the window list as soon as
: the windows process (e.g. shell) exits. When a string of  two  keys  is
: specified  to  the  zombie  command,  `dead' windows will remain in the
: list.  The kill command may be used to remove such a  window.  Pressing
: the first key in the dead window has the same effect. When pressing the
: second key, screen will attempt to resurrect the  window.  The  process
: that  was initially running in the window will be launched again. Call-
: ing zombie without parameters will clear the zombie setting, thus  mak-
: ing windows disappear when their process exits.
: As  the  zombie-setting  is  manipulated globally for all windows, this
: command should only be called defzombie. Until we need this  as  a  per
: window setting, the commands zombie and defzombie are synonymous.

For example, "zombie dr" makes it so the window won't close until you
press "d" -- or, if you press "r", screen will attempt to re-run the
program that was exiting.
