For some weird reason, one of my Woody boxes has developed a problem
running the default Midnight Commander package that comes with Woody
(V4.5.55-1.2) - 9 times out of 10 "mc" just hangs, and never displays
anything - if I Ctrl_C then I get back to the command prompt, with no
consequent problems. Occasionally "mc" still works as advertised.
I can't see any pattern to this at all (different user accounts,
different current directories, etc.). I *did* recently have a full
root filesystem problem, and had to add more space - might be involved
I suppose.
I tried removing and reinstalling (using apt-get) the package, but
that made no difference.
I tried stracing the beast, to see what it's doing at the time of the
hang - here's the tail of a typical example :

read(5,
The "read(5, " thing never terminates. When I Ctrl_C, the words "not
terminated" appear on the same line.
Anyone any idea what might be going on here (and what all that
"mremap" stuff is all about) ?
Any clues much appreciated.
