RHEL4 (I think).
svn 1.4.0

I ran strace on the unlock command and found it was hanging on

[...]
open("<repos>/db/write-lock", O_RDWR) = 5
fcntl64(5, F_SETLKW, {type=F_WRLCK, whence=SEEK_SET, start=0,
len=4611900633648188104}) = 0

so I guess there is some sort of file locking that got bugged by
someone's svnserve. The odd thing is that the unlock would eventually
run - maybe there is some sort of timeout for the write-lock...

There was one svnserve pid that, when killed, fixed this issue. He was
later able to connect normally afterwards.

Still no idea why this all the sudden started happening.
