Read the following excerpt from a US court opinion:
```
See Farmer v. Circuit Court of Md. for Balt. Cty., 31 F.3d 219, 223 (4th Cir. 1994) (“There is ... authority for treating sufficiently diligent, though unavailing, efforts to exhaust as, effectively, exhaustion, and for excusing efforts sufficiently shown to be futile in the face of. state dilatoriness or recalcitrance.”). Here, the West Virginia Supreme Court of Appeals took over 20 years to decide Plymail’s direct appeal of his criminal conviction. Our sister circuits have found much shorter delays sufficient to excuse the exhaustion requirement. See, e.g., Lee v. Stickman, 357 F.3d 338, 342 (3d Cir. 2004) (“[I]t is difficult to envision any amount of progress justifying an eight-year delay in reaching the merits of a petition.”); Coe v. Thurman, 922 F.2d 528, 531 (9th Cir. 1990) . The magistrate judge and the district court
