Since this happens when sending email, i.e. opening network
connections, I suspect that memory might be eaten up by reader threads
we start to support each connection.  This is further exacerbated by
the fact that Sebastien uses TLS connections for email, so perhaps
emacs_gnutls_pull is part of the problem.

Sebastien, if the latest emacs-24 binary still gives you trouble,
please try separate the sub-process and Helm stuff from the email
stuff.  That is, start 2 sessions of Emacs: one that uses Helm, but
does not use email, the other that uses email, but not Helm (or
subprocess-related commands in general).  I'd like to know whether
none, one, or both of theses sessions will exhibit some abnormal
symptoms after several hours.
