Ok, ktraces/kdumps on my system show that tar is exiting before
the last gunzip's write :(
gunzip.dump.human shows the last successful write on gunzip side and
tar.dump.human shows the read sequence on tar side.
gunzip has written 65536 bytes whereas tar has read 6 x 10240 = 61440 bytes
and has exited thereafter. gunzip has got successful
write operation (65536 bytes).
At last gunzip tries to write 4932 zeros and fails...
The command is exactly as above. FWIW:
~> echo $SHELL
/bin/tcsh
