 This seems to be a general problem with full-screen ncurses applications 
 - I've seen it with ee, sysinstall, sade and tzsetup. When the 
 controlling terminal is detached, the application starts using 100% CPU 
 until the application is killed.
 
 One of the backtraces I obtained from ee was:
 
 #0  0x0000000800878dac in sigaction () from /lib/libc.so.7
 #1  0x000000080066f282 in _nc_signal_handler () from /lib/libncurses.so.7
 #2  0x000000080066edc2 in doupdate () from /lib/libncurses.so.7
 #3  0x0000000000402552 in main (argc=2, argv=0x7fffffffebb8) at ee.c:622
 
 Without debugging information in libncurses I can't tell if there's 
 anything significant about it though.
