There is nothing currently in Cygwin that does RAM disks -- in fact,
Cygwin usually uses the underlying Windows filesystem drivers. However,
there are some things that are similar -- look at virtual filesystems like
/proc, etc. You could implement your own virtual (writeable) filesystem
that acts as a RAM disk, and submit a patch to Cygwin. With luck, it
should be integrated [it'll definitely be "Thoughtfully Considered"(tm)].
