Subject: [PATCH] fix: correr chdir de a uno por thread
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

como jekyll no es multi-threaded, pero rails si, es posible que se
produzca una excepción en Dir.chdir si se intenta leer sitios
concurrentemente (por ejemplo, abrir dos pestañas del mismo sitio).
