# VMALLOC -- Like malloc, but force the buffer to be aligned on a virtual
# memory page boundary. This feature can be used, e.g., in 4.XBSD UNIX
# to "bypass" the system buffer cache (to avoid copying file data from the
# system cache into the file buffer). VMALLOC can be made equivalent to MALLOC
# via the parameters in <config.h>, if the local machine which does not have
# virtual memory.
