	I've got the following problem on a Sun Sparcstation 300 running
SunOS 4.1.2:

	Several concurrent, cooperating processes are modifying a file.
Occasionally, this file gets trashed, and it looks like a flock() problem:
according to my syslog output, occasionally two processes get an exclusive
lock on the same file.
	I think I'm using flock() correctly. What I'm more interested in
is knowing whether anyone has noticed any similar problems.
