100,000 tries for an attacker amounts to 17 bits of security. This is as little
as nothing at all.

gpg-agent can remember passphrases for you. You could also look into using a
smartcard. With a conventional, on-disk key, the passphrase cryptographically
protects the secret key material, so it needs to be complicated to have enough
entropy. With a smartcard, you only use a PIN, say 8 digits. 8 numerical digits
is 27 bits of entropy, again nothing. But that's not a problem because the card
locks after 3 tries; the PIN is not used as a cryptographic key. Entering an 8
digit PIN is much less work than entering a good passphrase.
I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
