I took a backtrace using gdb: the offending code was in
libfreetype.so.6, and, looking at the source of freetype-2.1.10, more
specifically in builds/unix/ftsystem.c.  It could be more robust by
checking for directories, and it will hang on empty files.  But Plash
should really have read() return EISDIR on directory FDs, so I guess I
should wrap read() to check for this case.

In the mean time try adding "-t /usr/share/fonts/type1 /dev/zero" to
the arguments to pola-run.  (pola-run doesn't provide a way to force a
pathname to be unmapped in the file namespace, but this should work
for the purpose.)
