Normally it shouldn't be but I recently had postgres create ~13M .snap files and just opendir() took longer than anyone would care to wait... so it can be just as expensive. One could just as easily ask why create mode 600 files in places where they don't belong. -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu
