Forcibly terminated after 10 milliseconds

[Doug Luce]

After an OS upgrade (to FreeBSD 11 with pkg Dovecot 2.2.26) I'm getting this 
sort of thing in my logs:
  Nov  3 12:15:16 toma dovecot: lda(doug): Error: program 
`/usr/local/lib/dovecot/sieve-pipe/growlmail' was forcibly terminated with 
signal 15

Debugging gives a little more info:

  Nov  3 12:05:51 toma dovecot: lda(doug): Debug: waiting for program 
`/usr/local/lib/dovecot/sieve-pipe/growlmail' to finish after 0 msecs
  Nov  3 12:05:51 toma dovecot: lda(doug): Debug: program 
`/usr/local/lib/dovecot/sieve-pipe/growlmail'(11794) execution timed out after 
10 milliseconds: sending TERM signal

growlmail is specified via a sieve rule: pipe :try :copy "growlmail";

This would seem to be a function of input_idle_timeout_msecs in 
lib-program-client/program-client-local.c, but it's not clear where this is set 
(or why it would be 10 milliseconds by default).

Is there a way to up this timeout?

Thanks,

Doug
