thank you, Waclav.

I don't see any unnecessary space (or other CPU problems),
using another Linux variant (RHEL 5)
in the three R version
       	  2.9.0 ,  
	  2.9.0-patched (r48700)
	  2.10.0-devel  (r48700)

Can other Windows (or ...) users confirm problems in R 2.9.0 
(or newer) ?

I just tried it on 2.9.0 on the Windows GUI (RGui.exe)
and saw similar problems.  When printing to the
command window, with either print(val) or show(val) it took
a very long time and put $'s at the ends of the lines
(indicating that there was text beyond the edge of the window).
I used sink() to put the output into a file and then print() and
show() acted quickly.  The resulting file had 119 character
lines, consisting mainly of trailing blanks:

readLines("c:/temp/val.txt") # output of print(val);show(val);str(val)

[1] "     [,1]
"
 [2] "[1,]
"
 [3] "     [,2]
"
 [4] "[1,]
"
 [5] "     [,1]
"
 [6] "[1,]
"
 [7] "     [,2]
"
 [8] "[1,]
"
 [9] "List of 2"

[10] " $ : cplx NA"

[11] " $ : cplx NA"

[12] " - attr(*, \"dim\")= int [1:2] 1 2"

nchar(readLines("c:/temp/val.txt"))

[1] 119 119 119 119 119 119 119 119   9  12  12  32

On Linux, using yesterday's 2.9.0, valgrind shows lots
of 'depends on uninitialized value' problems that could
explain the Linux-Windows difference in behavior:

val<-matrix(list(NA_complex_,NA_complex_),1)
val
