I have not had the time to review the problem in detail, however,
I will throw out a comment which may shed some light on the problem.
Input/output operations on VAX Ada files take place sequentially
(see Programmer's Runtime Reference Manual section 2.7). Thus, if
two tasks request I/O to the same file, the second task will wait
until all previous I/O on that file is completed.
Although I do not know for sure, VAX Ada probably treats the terminal
as a "file" and, if it does, a write can not take place while a read
is pending.
