OK, so let me ask a bit more precise:

VED (and similar nvi) does record locking of edited files by first
opening the file with O_RDWR and applying a record lock. Then it opens
the the file for reading and reads the file into the buffer.

This definitely does not work with Cygwin on Win ME. 

-	Will this work on Win NT ?

If not, I could try to re-use the file descriptor from the record
locking call for reading in the file and later for writing it out.
But then there should definitely a fix in cygwin or a hint in the FAQ.
