Commitc1167a0

committed

Add 'temporary file' facility to fd.c, and arrange for temp

files to be closed automatically at transaction abort or commit, shouldthey still be open. Also close any still-open stdio files allocated withAllocateFile at abort/commit. This should eliminate problems with leakageof file descriptors after an error. Also, put in some primitive buffered-IOsupport so that psort.c can use virtual files without severe performancepenalties.
