Details:

I've been mistakenly passing a string to the "xticklabel" axis property a la

x = linspace(0,1,100); y = sin(x); plot(x,y);
set(gca,"xticklabel",sprintf("%14.8f ",get(gca,"xtick")));

where, you'll notice, the string is definitely not what get(gca, "xticklabel")
would return.  This causes a "*** stack smashing detected ***: gnuplot
terminated     " message from gnuplot 4.6 patchlevel 0, kills the pipe, and
leaves further plot(...) commands spitting forth "broken pipe" messages.

I expect the set command should fail but not take down the pipe.
