What does each connection do? Since Pth is non-preemptive, if a
connection does work that does not use Pth calls, then the connection
will block other connections.
For example, if a connection makes a query to an SQL database, this may
block the server while the query is in process. It is possible this can
be avoided by using the "hard" syscalls in Pth, since this will
intercept the I/O operations in libraries and allow other threads in
your application to proceed.

p.s. If you want to send me your code (or part of it), off-list, then
I'll be happy to have a look.
